Hey folks,new guy here.
I'm working on my first F head,1919 police. Probably be drivin' y'all crazy with questions and ideas.

My current dilemma is finding 20 over pistons. Anybody ever thought of using Tecumseh pistons? The HH80,HH100 and OH140 have the same 3.12" bore. Been trying to get the info on pin dia and comp. height. I've owned two OH Tecumseh motors and I know from experience they are tough as nails.

Next ?
IF I do wind up using such a beasty would it be a good idea to omit the oil ring.

Thanks, SW
