i can only find a max of 81.25 which gives me enough to bore the block .25 over. and they are $169 for the set with wrist pins. extra $100 for oem rings.

What kind of compression ratio could i expect with using the 81.25mm ctr pistons, 2 layer headgasket, and omni power high comp. valves? it looks like around 12:1, is this correct? ill be doing a full n/a build real soon, and liked the CR of the pct pistons.. price is nice too
