Default What are the best heads for a ls6?

Yeah I have a 02 Z06 with a magic stick 3 cam. I want to get the best possible hp/tq out of my setup. What heads would give me the most gains? I do not plan on going blower/turbo route. I want to be all n/a. Money is not a object here.

Money not an object???

Well, If I had that luxury I would go with ETP 215 heads on a stock displacement motor. Contact Andy at A&A Corvette and ask him about these heads. He had great results with them on a stock displacement LSX motor.

AFR 205cc are also very popular, very pricey, and very well made. Consistent results and lots of users so you can search the dyno section for their results.

Good Luck.

Check out Cartek for the best heads. The currently hold the record for the highest RWHP from a stock bottom end at 507.9 RWHP, this was done with a cam that is smaller than the MS3 and T-REX which is a testament to their killer heads.

The two most powerful heads for a stock block, 3.90 bore Z06, is the ET 215 and the TFS 215. The TFS do not require the optional rocker stands or relocating your alternator. Both also have more piston to valve clearance then your stock heads.

So if I want to get the most hp/tq out of a set of heads I should go with the et 215's? What gaskets should I go with also?
