I just went to a long rod +4mm stroke blaster piston set up and need to know what squish angle to cut my domes. It is a wk head and i think they cut the domes at 14* for the 795 pistons. My trinity head uses 12* on the 513. So will 11* work out ok on the 573 piston? The domes are 19cc cut for 4mm stroke and the 795 piston and all im wanting to do is match the band to the piston or do i need to order new domes?
