ls1 bore is 3.90; you need a 4.125 to use them

Over kill on your motor. Your motor can not pull enuff air to take advantage of the ls7 heads. IMO buy the heads and have a motor built to back them up.

Deadmans right, the LS1 bore is not large enough to support LS7 heads. They would make it breath really well though, if they would've fit.

Nope, still only a 4.000 bore. I believe they need 4.065 for the valves to even fit, and 4.125 to unshrowd them.

Meh, oh well. Probably too costly right now anyways.

Thx
