    I think that is a huge problem in the community right now is the lack of info on properly knowing where to stop when adding timing.

    Yes correct, I agree.

    You realize with the characteristics of the LSA, if timing really was the cause it'd have knocked a hole in the piston/broke a ring land before actually pushing the heads off right? LSA has cast pistons, and at 9.0:1 Cr, it'd have to take 14 more degrees of timing to even begin to change final cylinder pressure, and by that time would've been knocking so bad something else would have failed.

    FYI I ran 20.5 PSI on my stock CTS-V with only a LS9 Cam and headers..

    Made over 12 pulls. No head bolt or gasket issues.

    But i did have some Shell URT 105 mixed with pump gas.

    Good to know Mike. Ed knew I had MS109 with me and meth. I am not sure if meth or higher octane fuel would have prevented the heads from lifting. I am sure it was the combination of 20psi, 20 degrees of timing and 210 IAT2s, and 93 octane.
