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

so it was just valve seals? if that was the only problem thats not a casting/machining issue

Never been on a dyno... the butt dyno was a massive difference. I use to get moderate tire spin in first and chirp second. After the install full throttle in first is almost useless, second lays a healthy patch and I hook in third. The thing that I noticed most about the head swap is after 2200-2500 RPM.. the car pulls very, very hard. I can be rolling in second and floor it and the car is on the verge of loosing traction from 2500 all the way through the RPM range.

I wish I had the funds to take it in for a dyno run. It would be nice to see actual numbers rather than talking out what my *** feels... I am not sure what a dyno run would even cost in my area.

idk, i just want a good head, that i can grow with, because one day id like to be making some insane power.

thats why i picked trickflow twisted wedge, they can get me to 300hp easy, and down the road if i want to throw 10-15psi at this engine, the heads wont be holding anything back.



but that is my major issue right now, trying to figure out of trickflow's are really worth it, or should i just go with a cheaper head, such as patriots, or ported gt40p's

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...
Mike (Thumper) can do almost any head you send him. Lately he has been doing allot with the Mini Cooper heads if that tells you anything. He is an honest old school guy that will not BS you.

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.
How you do not see this as a problem is beyond me.

I have a set of gt40's witha f303 cam and rpm performer intake with a holley 650 double pumper making 370hp so if your only looking to make 300 that should be easy as hell. Now if you were trying to make 400 i could see the problem but 300 aint all that impressive.
