I run pump premium with 10.5 and iron heads. Shouldn't be a problem with 11.0 and aluminum heads.

Warmed block to 200f and found deck grew .015. Will make pistons to be .008 above cold. Should hold quench below .050.

"Pump Premium" has different octane depending on what part of the country. Do you have 93 octane available?

My 427 has 11.7 C/R. Aluminum heads and adequate roller cam. It runs nice on our local 91 Super.
