i use conventional i took the cylinder head to a machines shop to get a new seat guide seal and bearing the piston is 1 over new piston and ring and new bearing i put it all together and i im sure that the ring are stagger the right way im thinking its the seal due to compression is perfect im hooing some one else had this same issue im gonna try to drive the car hard to beak it in this week
i have a new rebuild engine almost every thing has been replace on the engine it runs good has alot of power but my issue is it smokes lightly when in idle and it would smoke alot when deceleration some time its smoke alot on aceleration some times it doesnt any idea compression is with in 2 psi so compression is good head has been redone and new valve guide seal
