Default Z06 Heads?

Ok guys, are the Z06 heads significantly better than the stock C5 heads? Would this be a worthwhile upgrade?


TiA,

YES. You can get some ported and polished LS6 heads. Much better air flow. Combine with a good cam and let the begin.

Default Add a cam at the same time!

I added a MTI R1 cam to a set of mildly cleaned up 243 heads (& LT's) and pulled 420 RWHP.

The heads are an improvement over the 241/853 heads. Since you already have the topend off, pull the steering rack and do the cam.

It will make you smile!!!

I wouldn't bother unless you are going to port them and throw a cam in.

Heads with no cam are not worth the cost. motor is like a air pump a big restriction is the cam. (this would be first thing I would fix most HP bang for the buck), then heads, then air intake then exaust in this order. cam lets in air longer and opens valves higer.

I now have the 2002 LS6, ZO6 cam,LS6 intake and shortie headers it is a great improvement over the LS1 heads, cam and intake. I dynoed 349 RTWHP and 351 RWTQ with this setup. But as the mod bug has bit again, I'm removing the heads and cam to go with a larger cam and Patriot heads in a few weeks.
