Default whats your cylinder pressure? look at mine

ive got a 418 flat tops with valve reliefs, and 317 heads 72cc, and a vindicator cam. i got the motor in finally and to make sure the stock push rod length was gonna work i was told to do a compression check.. so i did and got 250psi

so i called my machine shop back and told him and he said thats WAY to high.. and he said to call vengeance racing to learn more about that cam.. they said that cylinder pressure is right where it needs to be.. so right now this is whats going on and i dont know whats right.. but i am gonna fire it up today and see what happens.. machine shop said its gonna detonate real bad at idle..
