90 over 318 Head Gasket info needed !!

-
Nothing cooler than finding vintage upper end speed parts wrapped up in the box still coated in cosmoline.
 
Two things....

That FelPro 1008 head gasket can handle the 13 1/2 compression in my small block 383 on dirt.

Am I the only one who noticed that the Chrome-a-shaft logo looks familiar? One of Comps old companies...
Good observation

One of my engine guys who is a Chevy guy always says "when is the last time you saw a broken Mopar crank?"... The answer is usually "never"...

Is .090" over on a 318 even doable? Just curious, as I have only done big blocks. We usually go .020, .040 or at the most .060, but 60 is pushin it! How much overbore will a 318 take? Is 90 the max? Thanks.
Hensley Motorsports has been doin it thirty plus years on their crate motors.
 
Rusty hard to convert those who believe the Mopar books are the final word .
I know. Hensley has gone over 4" with 318 blocks. It's all in what the sonic test says. Ain't you usin them for some of your sheen work now?
