stripped cylinder heads down today and checked installed height and psi, found on average the installed pressures were on average less than 30% of what they should of been
Valves stem seem tight in guide
margin doesn't look that bad, although need to measure
I may end up keeping valves and throwing out the springs, retainers
engine block and bare heads in pot cooking tonight for 24 hours
One 8.5Kg gas bottle will do 24 hours, with 8 hours of brew boiling
