Default List your L92/LS2 heads & cam combo here.

Hey guys.

Like others here I'm looking into adding a L92/L76 package to my LS2 and i would like to see some proven combos.

Please list your L92/L76 heads & cam combo or heads only combo here. Don't forget to list what cam you went with and other supporting mods. Also, don't forget to list your RWHP/RWTQ if you have it.

Thanks in advance.

05 Z51 Mn6: L92/L76 combo stock heads and gasket .020 milled, ported intake/tb, 224/228 114 LSA cam, Melrose 1 7/8" headers, VaraRam, 440 rwhp/405 rwtq. To note, the ported intake did not produce any further hp just 5 more on the torque....although the throttle response seemed to improve. Also, there was no fly-cutting on the pistons....enough clearance with this setup. Not track action as of yet.
Later, I may try the .040 cometic gasket for higher compression.

I had DTE do the L92/L76 upgrade to my 07 M6. Along with the heads/cam, I added Dynatech headers, K&N cai, Corsa sports, and underdrive pulley. I went from 353/357 stock to 460/432. The car had 450 miles on it when it underwent the surgery. I don't know the cam specs, but it's a small one - maybe a 3 out of 10 in size. I wanted reliability and driveability over numbers. It is absolutely perfect for me.
