To add to this; DE piston dish is slightly larger than the Combustion Chamber of the VE head. What this means, is if using DE pistons, that equates to a bump of compression by 0.6-0.7. So, if using DE bottom end with 8.5:1 pistons, with using a VE head your static compression will be 9.1-9.3:1. Not a big issue if one is aware, but something to be aware of (and absolutely agreed on the valve relief comment)
Anything 9:1 on DE pistons "should" (emphasis on the should) a safe bet with P11 cams. Anything higher in compression, I would not recommend.
OP, please do a search on the forum for the VE thread. Not interested in spoon feeding at this time, sorry
