Sure do. its 14096217 they are pretty new heads, think they were used in crate motors a while back. I agree with the particle contamination and low oil pressure. Ill make sure i Plastigage all the journals
Ill probably be starting the build in a week or so so ill let you guys know how it goes. I mean i was having serious issues with my oil pressure. On a cold start i would have a good 25-30 but when it was warmed up completely iv seen it as low as 3-5 at idle. I wont have these issues this time around but what could have caused this for future reference. I was thinking big clearances or something i was missing not sure.
