Haven't heard much feedback lately so I continue to plow into this.
Riki: 'Top' is facing the head in this picture. Still don't get why the gaskets don't match the holes in the head/block. Like the big round one in the middle. Seems like that coolant should go through there and not have the gasket stop it.
Took out all the lifters and the camshaft. Seems like oil everywhere but 4 (#1 Intake, #1 Exhaust,#4 Ex, #7 In) of them show wear signs that they are not rotating. They seem to rotate easily by hand when installed. Example picture below.
Pulled the camshaft while I was at it. Some wear evident but also all surfaces coated in a light film of oil. Here are pics of the front cam bearing and the corresponding camshaft journal. The bright lights from the camera seem to make it look worse than they do by eye.
Took my heads to the shop that redid them. They looked them over and said all looked good to them. Suggested that I look for a vacuum leak esp where the intake manifold meets the heads to maybe explain why the front 4 cylinders appear to be running rich while the back 4 are not. They didnt think the standard, thin metal gasket would cover much in the way of non-uniformities across the mating surfaces. So suggested I make my own out of thicker gasket material or use Ultra Gray (instead of the Copper Coat I used).
More to come. Any thoughts would be helpful.
thx
