i guess it pays to be a machinist and have friends with machine shops[8D]

seriously, like i dont ever think about these things like they could ever present a problem. last week or so i needed to do a vavle job on a 1.3 L SOHC suzuki so i just brought it over to my buddys and gave him a 350 4 bolt main core i had in the garage in exchange for him letting me use his equip [8D]
sounds like you got off the hard way. you could have sold that block for an easy 500 bucks. thumper heads appear to be a nice sleeper mod. makes me wonder what can they do with other heads if anything...

dude i dunno where you live and can get 500 bucks for a 4 bolt 350 core, but around here they are easily found and if they are std. bore they are worth about 100 to someone who needs one and 50 to someone who doesnt really need an extra one.

Well if i fully port a set of GT40P's how much of a power increase can i expect?Would a 1.94 intake valve help?

hard to say an exact number of gains but there WILL be gains. tristatecylinderheads.com has GT40P's with big valve and stiff springs ready to bolt on for cheaper than you can buy a set of junkyard heads and then do the work and buy the parts.

but if you are going the other route, putting a 1.54 exhaust in the head would be a better investment than putting a 1.94 intake in it.

Hey guys is it me, or did everyone miss the bus on this?. On his second post, he asked if the GT40s will work with his 331?.mxrider426, I'm not trying to bust your chops, nor am I an expert, but that E cam will suck if you are running it in a 331. The 331 requires some type of aftermarket heads, and a much better cam than the E cam. You could probably get by with some GT40s, if they professionally ported, but you need to look at a dual pattern cam, better yet a custom cam for your stroker. I learned the hard (see expensive) way. I did find a brand new pair of Twisted Wedge heads, with new screw instuds, and new FRPP roller rockers on the Corral Classifieds for $1260 shipped to my door, but since then, I sold my F cam and went with a custom cam, had to scrap the TW springs and retainers for some Comp Cam pieces that better match my cam ($550 for custom cam, new springs, spring seats, retainers and keepers). I would at least look into a Comp Cam dual pattern cam, along with some TW heads, or AFRs. I know it's a lot of money, but you will be much happier with the results.

I love how everyone jumps on bandwagons around here.... I have patriot heads and have been very, very happy with them. The first sets of heads for the 5.0 were on the low quality side. I don't think this has anything to do with thecontinued quality of the heads. All new products go through a period of adjustment until bugs are worked out. Patriot spoke with me freely when I called andasked them about the posts I was reading concerning quality. I did a lot of research on these heads before I got them. One thing I noticed was almost every post I read about the "nasty" patriot heads started with "my friend..." " I heard..." "I read..." I looked for days before I found anything that was first-hand knowledge. I have no regrets with my purchase.

+1 on the Explorer coming with GT40 heads, before the introduction of the P-heads in 97

Agreed. The Patriots are a very nice head for someone that wants to get into a aluminum head but can't afford the prices of a higher end aftermarket set. They are a great affordable option besides just porting your stock stuff. The problem is, people like to compare them to heads that are almost double the price tag, of course your going to get more for your money when going with higher end stuff. For the regular enthusiast, looking for a bump in power and save some money at the save time, Patriots are a fine way to go.

If I had the option, I'd personally take the Aluminum Patriot heads over a set of worked Iron GT40's.

Well im not a complete dumb *** about engines. I know a 331 would need better than an E cam. And did you read in another post that my uncle owns a cylinder head machine shop? Im just trying to get opinions from people on which would be best to go with on a budget. But anyways. . . Bottom line what should i do. Port the E7s, port some GT40s, buy the Patriots, or buy used Edelbrocks. I will throw a stock piston 302 together if i have to depending on the heads. I have plenty of them

For a budget build, since you already have the E-cam, I would pick up some gt40s, and have your Uncle port them, along with a 3 angle valve job and you'll have a pretty good iron head. If you can find a set of used aluminum heads that aren't trashed, that would be even better. Unless your flat tops have valve reliefs,you'll be limited to a 1.90 intake valve. Edelbrock Performers (part 60379)&AFR 165s will work, as willthe Twisted Wedge heads (they have 2.02 intake valves, but work with stock pistons). I haven't heard of anyone trying the Patriots (2.02 intakes) with stock pistons. I would think there would be PTV clearance issues.

You are an example of real world experience and also part of the reason for my negative opinions on the patriots. IIRC you installed these heads and had to take them off and send them back for repair. Then there are the pics Ed Curtis posted on another website. I'm sure he did not buy several sets of patriots untill he found some that had problems. Untill a few people post that they have bought these heads and had no casting issue's or other problems than maybe we can say they've upped the quality of their product and have stopped sending **** out the door to customer's. Dont you still have the stock cam in your engine, that could explain why you have no clearance issue's. I've HEARD that most have problems with clearance when using OTS after market cams. As i understand to have a descent grind you must get a custom grind?

I'm not following you on the "You are an example of real world experience and also part of the reason for my negative opinions on the patriots". I did have an initial issue with the heads, they were shipped back to Patriot, repaired, shipped back, put on all at no expense to me. Why would that be a bad thing? I called Patriot and spoke with a real live person and they spoke openly with me about some initial quality issues. They did not make excuses and made it right. Great customer service in my book and I got a set of heads that significantly improved the performance of my car. So why would this reinforce anyones negative opinions?

The first set... several of the valve seals backed out. Patriotreplaced all of thevalve seals along with the valve guides. I am running a stock cam - I ran out of money on the last repair so the cam got scratched off the list.

You say they were sent back to you and put on with no cost to you? So your saying that patriot payed for the labor or did you or your shop install them?

Patriot paid for labor, gaskets, fluids - everything. There was nothing else I could have asked them to do.
