Assembly has gone along pretty well---ring gaps and side clearances OK, con rod side clearances OK. Main and rod bearing clearances OK--by OK, I mean well within the oem specs from the FSM.
I got the cam and lifters in and used the oil pump shaft and a cordless drill to pre-lube. ,I saw over 20 psi on a mechanical gauge installed at the left side of the block near the end.
What I didn't see was any oil coming up the head bolt hole for the rocker shaft. Does it need more pressure to pump up there? Seems to me I should be seeing something.
Also three of the original head bolts seemed a little "soft" as I tightened them to the 1st round spec of 55 ft lbs---one actually broke before reaching 55 ft lbs.
Are ARP head bolts available, or is there a better way?
