150-160 is actually normal compression (9.1-9.5:1).

Subject: DML: engine compression.
Well, i'm finally assembling my engine. But i'm trying to figure out
what compession i need to up to to match my hughes 1418 cam. I know that
huges says it need to be at 165psi. if normal air is at about
14.5psi@sea level than 165 translates to about 11:1, is this true? I
think I could figure it all out on my own if i knew the deck height of a
318, but since i dont(neither does the machine shop) I have to pose the
question. Is the stock 9.2:1 compression ok on this cam, or will i have
to mill the head a few thousandths to achieve a higher compression and
the benifits of the cam. does anybody know the deck height of the 318? I
feel a little bit lost here when it come to the compression part of an
engine. And if i need to shave the heads, does anybody have an idea as
to how much i need to take off? Thanks to everybody for the help -Aaron
