I got a h22a eg with a built head and stock block with a few good boltons. I got a dhracing 1layer hg for a compression bump to 11.1:1 but I'm doing a rebuild and wanted to know what's a good,safe and the max amont to deck the head and what kind of compression ratio I would be at and how much pressure is too much for these notoriosly weak h ringlands......chime in

 

So no one here has ever decked a head for an all motor setup it seems like.......bump

 

You might have more luck in the All Motor forum.

 

Only thing that comes to mind is check your p2v clearance

 

p2v = *boom*. :0

buy some clay or some playdough or something and check your current clearance. If your compression is already 11:1, then your p are probably dangerously close to your v (giggity). And, iirc, a "built" head usually means that you can expect your v's to open farther down than a stock head (my apologies if I am wrong on this...i am just a hobbyist).

Basically, I think you are on a thin layer of ice and you are moving towards thinner ice. USE THE CLAYY!! (haunting echo voice)...lol
