Hi, just wondering if there was any way of identifying what pistons are in my cvh. i bought the engine a fair while back from somewhere thats been slammed by a few peeps on here for charging for work and mods not carried out. so anyway gonna whip the head off and check that but want to know if the pistons are in fact the low comp items i believed them to be. can i measure bore and stroke etc to work out comp ratio accurately?

also if anyone knows the size of standard head ports that would be great.

thanks in advance.
