cometic head gaskets

bry-war · 06-18-2017, 11:55 PM

I have a big Chevy from Schmidt that failed between 5-7 due to cutter marks using cometic gaskets. Only posting to say that composite is my only fix but why is the cutter pattern not the same between bores. It's as if the block machine was cutting at angle (side to side) making most of the between bore deck verticle pattern and others a bit more /// direct between bores. Is there a standard for deck tooling path? I just assumed parallel to crank. Sorry if I'm hi-jacking.
Thanks
Bryce
