When I spoke to the machinist he said he definitely did not take 0.100” off the heads - he remembers working on the heads for me but seems to think 0.040” is more like it.
as for cylinder quench area. With felpro blue .040” thick gaskets and factory low compression (1974 318) pistons I’m not worried about anything destroyed.
The LD 340 was drilled for the line up pins.
The engine ran fine it just was loosing oil and obviously burning it looking at the plugs. I’ve decided to install a set of 273/318 port sized gaskets, new plugs and reassemble. I will leak down the cylinders before assembly. I can pull the heads but not sure what that will bring me other than more questions. Even if I spend $40 on new gaskets and rtv the ends and run it over the summer and in the fall pop a new engine in the fall. If I send a used engine out to be rebuilt- it will take weeks if not more. Damn Subaru and Honda motors now occupy machine shops time. No money for them in old iron rebuilding. Anyhow. Thanks for the input. Syleng1
