OPS 21 Squish Band

[Chris Thomas]

Hey guys , going through the boats/engines for the new year. I am cleaning up the sport 20 and cannot find my paperwork for tolerancing. What dimensions are you using for squish area for a pretty hot OPS 21 on 40 percent nitro? Thanks for the info...

If you are talking about head clearance.... .012" should serve you well.
