The 233/239 would be the biggest being very close. But All engines vary so ????.

What is the biggest Cam that Texas Speed would recommend running with these heads?

Guys, we can set these 2.5 LS6's up so that they clear with as big as our MS3 camshaft! For a bit more clearance, try the Tsunami

Well Im running the MS3 on a 113 LSA-But I also have a -4cc dish piston. With these heads. Cept I have an older set with a 2.04 intake valve. Being reused on a newer set soon.

Damn these are very tempting my cam should clear no problem.

In your in house testing, what is the typical gain on these over some stock ls1 untouched heads?
Would 40 RWHP be out of the question?

Sales2@Texas-speed

On a 6 speed car that is a very feasible number from the testing we've done here. Of course auto cars aren't quite as dyno happy though

The heads will pick up on a basically stock motor. We have customers run these heads with 220 and 224 duration cams all the time with great results!

Could you possibly post a picture or 2 of the chamber work? I've seen quite a few of the runners, but nothing of the chamber.
