I have a mate building up a 103 from a stock twin cam. He picked up a set of brand new 110 heads and I looking at using 103 pistons part number 221408B. I have reading the Piston combination compression ratio chart from 2013 SE book, but I read a older SE booklet (2010) and its cylinder head Piston combination compression ratio chart read deferent as it had a column for the 110+ heads while the new booklet does not. Okay thats the run down and the question is do those pistons fit with those heads??
