Valve clearance

[czakky82]

Just for the heck of it I did a leak down test and it was close to perfect. Maybe a 4% loss on the right and less than that on the left. The right seems to have loss through exhaust valve of which there is no evidence of of the exhaust valve making contact.

What are the odds I can put the correct pistons in and be okay?

I’ll of course have the heads and guides examined.

You could just have the relief machined into your current pistons. Definitely look at the intake valves to make sure they're straight.

That’s what I was thinking too , and you have perfect locating marks!
