Hi rob
Steve was warning me about some high compression kits out there I bought the barrels and pistons from ebay....
Thinking of doubling up the base gaskets, it's my daily rider don't need to radical, what do you think?

The 4255PS code on the crown only comes up with 10.25 - 1 comp in all my searches which is the std compression hike for most wiseco road kits and is fine.
However if yours is an obsolete and no longer listed kit which is higher comp (usually a jump to 13 -1 for drag race) then a barrel spacer is the way to go.
