How many of you guys are building your own engines? I have a question! We're
building an 05 636 to run on methanol for Micro-Sprint racing, We're using Total
Seal rings on pistons, And we're using the thinner head & base gaskets to get
compression up a little more. My Question Is! We don't know how tight we can go
with the Valve to Piston Dome clearence before we have catastrophic results! We
did clay molds between the head and piston, it looks like we're at around 10
thousands right now. Anyone know how tight you can go before you wreck one of
these motors!

Thanks, Roger D.
