Well, I tore the heads down this weekend and was pretty disappointed by a complete lack of lube used during factory assembly! Valve guides and locks were dry as a bone! No back cut on the valves and a nice chunk of metal about the size of 2 grains of rice came out of one of the castings. The castings themselves look really good but it just goes to prove, yet again, trust no ones work but your own! Doesn't matter who supplies your heads. Always tear them down and inspect them for yourself! There, time to step off of the soap box now .
We went ahead and set one of the heads up with checker springs placed on block without head gasket and had plenty of clearance from intake and exhaust valves to pistons so no worries there. Head gaskets are Cometic 4.380 with compressed thickness of .040. Perfect fit for my .060 over block. Also completed was check for proper pushrod length including thickness of head gaskets installed and minus .010 for thickness of pushrod cups. I completed some minor port work and I mean minor. These castings out of the box flow well but there are some sharp ridges on the intake ports which needed a slight massage.
Dad will be taking the heads to Chuck's speed center to have them check the factory installed valve guides for proper alignment and clearances, back cut the valves, double check valve seal to seats, and shave .010 off to bump compression up a little more. Correct springs, retainers, and locks to be ordered this week and we should be able to finish building the heads in the next couple of weeks.
The transmission is built and a 4000 stall converter will be ordered soon as well. Won't be too much longer and I will be able to trailer the car up to my Dad's shop for completion of wiring and engine install .
