ok so im back with a couple more questions guys. with a build this size would it be smart to go with some aftermarket heads or will the stocks flow ok for now? and if i do get some heads what would be a good set for them? would jus a cnc ported and polished set be ok or would like a zzp stage 2 or 3 be far better? also is it really that big of a deal to go with the thicker head gaskets? i havent herd to much people doin it so? also anyone know of any good boost controllers?
