Re: CR for 5.3 heads milled .015..
with them completely stock (even the valves) would net 11.04:1 with a 60cc chamber and a .054" gasket..milled .015 would get you 11.18:1 ...but de-shroud the valves and slap in some 2.02/1.57's and come out to around 62-63cc's say 63 with polished chamber and deshrouded..that would get you 10.63:1....Later,
