We are both after the same thing, and that is cylinder pressure. We just have different approaches.
I accounted for the altitude in my suggestions by recommending a little more compression, and camshaft, than I actually used in the build that eventually went 12.30s. That build started at 8.8:1 and had a 218 @ .050" cam with 273 rockers and it went 12.90s. It was at 9.06:1 with the same cam and 1.6 roller rockers for the 12.30s.
Of course he could solve his altitude woes buy adding 6-8psi of boost.
