My engine assembly proceeds. I got the flywheel bolted on tonight (torqued to 150 ftlbs) so did a first test fit of the block. Studs are all in place and the block is loosely bolted down on a silicone gasket made from baking sheet. With the head (a Ruby one) just sitting on the studs and no head gasket in place it seems the valves hit the head. With a copper gasket there, but nothing torqued down, they clear. That doesn't seem like much clearance to me. How much clearance should there be? I haven't set the valve clearances at all yet of course. Just wound them up to lightly touch as a quick test. Is the only way to tell to have everything torqued down and adjusted?
Of course I don't know how much has been skimmed from the head in the past.
Another question is with the copper head gasket. Does the side with the copper flange wrapped around go to the top of the bottom?
I haven't done the rods and pistons yet but that will be next to check how far they come up the bores. Is it wise to do a test assembly without rings to measure that first?
