I think im gonna take your guys advice and go with the AFR 165 heads...Where is the best or cheapest place to buy them from? How much does an assembled 58cc set cost? how much of a gain do you think ill see goin to these in place of my gt-40p heads?

306
gt-40p
cobra intake-ported lower
70mm throttle body
bbk cold air
E303 cam
stock MAF and injectors
roller rockers
all the other bolt on stuff
373's

c-4 tranny 3500 stall

thanks for the help

Well as far as HP gain I cant say But you should be about 300 to the rear wheels or so with them on there I look all over and here is one of the best place to get them JD's Performance

PS. might want to get a new mass Air and 24's for it to run best.

Thanks alot for all ur help...soon ill have some AFRs :D
