Can a block be resleeved to go 4 mm larger? or is that too large to try to resleeve it to? also, if that is possible to do, what would you use for a headgasket, or would the stock head gasket work, even though the cylinder walls are now 4 mm larger? any thoughts anyone?

 

I have seen blocks sleeved up to 85mm. Cometic, Golden eagle and a few other companies make headgaskets especially for larger bores sizes. I beleive GE uses OEM gaskets and bores them to what ever size you need.

why would you want to bore it out that big, you don't wanna leave any room incase of errors or boring later down the road?

 

it's more or less for convenience then because i want to go that big - i have a motor that has an 83 mm bore and i can use rods from another motor because they are the same, and i could use those pistons too if i can resleeve and have that big of a bore on the motor, which is 87mm. if i can't go that big, then i would spend the extra money to get some custom pistons made, but i think that would be more expensive - i haven't looked into that too much yet, i was just checking my options first.
