Anymore opinions or suggestions?? There are crap loads on e-bay and i'm a little confused. I am running 10:1 comp. 1.6 RR & an Isky 264 Mega hydraulic cam with a bigmouth base,slp runners, 24# SVO'S, 52MM TB 350 block with 85 TPI setup. Please forward me some links from e-bay with some head suggestions that would be a good match for my setup.
Thanks

They are selling refabbed 305 heads . Well the 416 casteing is anyhow. They only have pressed in studs . They springs arent THAT great. But if it's in your price range ...go for it . But they are way better choices out there.

also, how do you know your compression w/o knowing what heads you're gonna use? - not possible - Why not look into Vortecs?

the aluminum vortecs(Fastburns) will bolt up to your TPIS base, with thick intake gaskets. Regular iron vortecs won't. You can mod them to accpet it, but everyone bashes people who do(I've done it a few times now, no problems) as for pricing(on the fastburns), unless you find a good used set, you could buy much-better aftermarket heads for less $.
