I just received my Heads back from Katech Performance and damn they did an excellent job my 408 should have no issues breathing

Nice! I considered sending my LS3 heads out for CNC but considering how well they flow in stock form decided against it. Are you making any other changes and how much do you expect to gain?

My buddy sent his Z06 out there to "fix the heads". That, a cam, a tune, and Borla exhaust were good for 560rwhp.

The cam company selection is also top notch.

I'm jealous! Wanted to do that to my 243 heads, but just couldn't justify the expense for what I'm doing.

Those heads look great, and that's a great choice for any build that you're looking to squeeze the last ounce of HP out of.

I have to admit that someday I'll do the same with Texas Speed, Katech, Chad Speier, etc. But it is hard to justfy another 20-40hp for a street driver in the 400+ range.

What are you goals with this car/motor?
