How much would CNC LS6 heads benefit a D1SC setup?

Well for starters it would make the same power at a lower boost level which would be easier on your motor and it will run cooler. If you can afford the heads definetly get them if you cannot afford them just go without them. You will just have to up the boost for the ported head power.

Depends what kind of HP hoals you have in mind. I made 550/460 on stock heads with upgraded valve springs, a small blower cam, and D1SC at 8psi or so.
But like 52172 basically said... they certainly wouldn't hurt!

Velocity. take for instance...this is about a mustang but u'll get the idea. I have a friend who had a 306, 205cc heads, 14lbs of boost, big intake and cam...he was only doing 120mph in the 1/4. He go tired of it not running what he thought it should so he sold the shortblock. Now, my other friend bought it, put a cobra intake on it, stock 302 cam, out of the box Edelbrock RPM performer heads (165cc) and 12lbs of boost. because of his gearing he hits the limiter before the 1/4 mile but he hits 130.9mph.
Velocity
so if u want any type of head work done (which u probably don't need now) then get ur LS1 heads worked on like bowl work and a good valve job.

I'm saying bigger isn't always better. he has a 306...205cc heads were too big. The other guy had his setup missmatched, he didn't understand how to make the proper setup. I'm NOT saying CNC LS6 heads are gonna be big, no way. what I am saying is u don't need those heads to make good power. If u were able to get ur LS1 heads worked with a valve job and bowl work, that's the way I'd go on the factory cube motor. If u want to save ur money for something else then that's fine. our heads have pretty damn good velocity, u'll be fine for now.

Same here. 10psi of boost, small 224/224 115LSA blower cam, stock heads/stock shortblock, and no Meth injection yet. I'm at 617rwhp/572rwtq at 6000rpm and trapping 130mph.... So its all about your power goals. I'm building a forged motor now with hand ported LQ9(317) truck heads, going to run 15psi boost with Meth inj. and shooting for 800rwhp....
But CNC LS6 heads will not hurt anything. Just not needed to make 600rwhp...

Some of pushed more power without any problems, but many more have had to have an unplanned engine rebuild. Bob
