ask thumper, and 90mustangtGT mise well be the poster boy for him, lets not make this a big thing like it usually turns out to be
I agree, lets not let this one become another one of those treads!
I don't see where I promote thumper's heads anymore than any other of his customers?
I just dissagree with some people saying they give little or no gain and are complete junk as some suggest.
Having your stock heads rebuilt by a reptable machine shop and builder, valve job and all, and then counting the time and effort of porting yourself, along with supplies, and parts, the prices for powerheads and Thumper's is a pretty good deal. Plus, there is more to porting than just hollowing out ports, you need to know what you are doing, and for the price I'd rather have a pro do it.
Is all this worth going through for stock heads? That is the question. The aluminums clearly have the advantage, no doubt about it but...
Are the aftermarkets actually a better deal? Well, I'll put it this way. If you are mostly stock on a budget, not really because you need other parts to feed them so the results would be similar. If you already have a good flowing induction system and a free flowing exaust, yes. Speed cost money, how fast do you want to go?
