So come to find out I will not be able to work these heads how I want (mill them down to 62ish cc's because it would mess up the valve geometry and I would have to buy and rework allot of stuff to do it) and I have to get stronger springs in order to run the cam I have... So depending on which is cheaper I will either buy a different cam or get a spring and retainer kit. I am also looking in to a possible set of E7 heads locally so even if it is slightly more expensive I will have better flowing heads and not have to put as much money in to the setup...

Ideas would be GREAT right now
Just remember I am on a budget, no AFR's or anything over a couple hundred bucks for me

Thanks a bunch and God Bless,
Brian

That will give you more insight as to whats going on, but its an 84 302 to answer your question.

would some gt40 heads work, i dont know much about 302s, but i think you could find some at a junk yard or ebay or something.

Here is what a guy locally said...

"$20 for the pair. Completely virgin heads, pulled off a running car. Still has original crud accumulation

The springs are a tad bit old (130,000 miles), but the valves themselves look to be in good shape(from what I can see, and they're still mounted). Probably need new valve stem seals too. 7/16ths head bolt holes, pedestal mount rockers.

A good cleaning, springs, valve lapping, and seals should do it to make them operational."

Unless there is a HUGE crack in the heads I am going to buy them... for 20 bucks thats well worth it, even if they need a little work.

20 bucks is a steal i wish i could find some 390 or 427 heads for 20 bucks

$20 for a set of rebuildable E7 heads is a deal. I'd say go for it.

E7 heads are not exactly "high flowing," but regardless of what you do, I'd get the right springs for whatever cam you run

KBunny

Yeah I know that the E7 heads and almost every (except for the GT40) stock cast iron Ford heads are poor flowing heads.
However the fact that the heads I have are 70cc and the E7 heads are 62cc will make some difference as is, and if I mill down (about $70) the E7 heads (which I just got back from getting them) to 60cc I will have a decent comp with the cam that I will be getting (http://store.summitracing.com/partde...p;autoview=sku) and I already knew that I will need springs and retainers for the cam (http://store.summitracing.com/partde...p;autoview=sku) so now the only question is do I risk not doing a valve job on these heads (130k miles) or do I just suck it up and spend another 130+ for a valve job?

The E7 heads aren't that bad. They're astep up from anything before, they're just not quite as good as GT40's. But for $20 it's well worth it
