just wondering if id be able to use a 75.5 overbore h/g on a stock 75. block. came across one still in the package, or whould i just sell it and get a stock one?

 

do it, you will be fine.

 

I would say you will be okay because Honda OEM HG come .5mm larger than stock bore as well as most replacement HG. The reason is because of a tear down and rebuild of the block and they dont want to put a larger gasket into production.

 

exactly, thats what my answer was based on, i just didn't want to type all that.

 

:chuckles:

OP, You're good to go, but I would stick with OEM, just my .02

 

its a cometic gasket or i would be using a oem one thanx for the help.
