EDIT: NEVERMIND!!!! somehow the oil sending plug got unplugged

just started it up...


smooth idle, sounds good (deeper and smooth).

there's smoke coming off the manifolds, which im guessing is the loads of nut-off i put on all the bolts. any one else have this situation?

but mainly, my oil pressure is very low, but my oil is topped off. i only ran it for about 1-2 minutes, cuz i need more coolant. has anyone's oil pressure started low but rose after a few minutes of idling? please help!

could it be the oil pressure sending unit? if so, where is that? thanx!!!!!

Did you block off the oil port on the backside of the heads?

This is important. There are some oil plugs that are removed from you old heads and put on the new.

nevermind guys, the sending plug was off the screw, everything's good. im gonna make a post about my thought on going from just the pi intake to going to full headswap, considering im mostly stock.

and yes, the first things i checked were the 1/8" npt plugs in the back

If those weren't there, all his oil would be on the floor in under 30 secs...
