I’m hoping someone from Hydrotec can chime in. Can anyone tell me the difference between cutting the stock heads on a 3.1l and the Hydrotec heads? Different chamber/squish band? Cranking psi with the recreational heads?

No difference....we start with a set of factory heads. On my compression gauge I see around 135-140 psi
