I need some help deciding which heads to buy. I can get the GT40Ys for $700 brand new assembled. These will be going on a 302 with edelbrock performer intake with ported lower and powerdyne bd11a currently running 6# and soon to be running 11psi.
GT-40Ys or thumper heads

On a boosted engine flowrate of the heads aren't that critical. I'd go with the y's personally but either of them is a good choice.
