My compression test came back 220 200 210 238, any suggestion what the problems could be... I am running Endyn rollerwaves 12:1 compression with toda C ......

 

.....did you do a leakdown test too?

 

Yeah, leakdown will let you know if your in real trouble!

What bore of piston did you use? Who honed the block?

 

who assembled it?

 

Did you have your cam gears adjusted +, or - ?

 

Don't sweat the numbers unless you really feel your losing power or something else seems wrong. The spec-C is a big cam even on the low cam. The duration and whatever your gear settings are can cause low numbers. Granted those are suppose to be pretty hi comp pistons but until a leak down is done or you suspect something worse dont worry to much yet. Be sure engine was at operating temp and was WOT with all the other plugs out, I know seems basic but just wanted to mention that. YOu can try that rislone ring seal additive that helps sometimes with engines in which the rings didn't seat to well. I think its something you add to the oil only once leave it in for ?? how long or how many miles then drain and refill with fresh oil. HTH Goodluck

 

Don't like the imbalance to much thats the thing that really worries me.

 

those numbers are low. try a different tester first.
