Swung by post office and picked up head gaskets I bought from member "75 Duster 360". Thanks again Rob!
A set of used Cometic measuring 4.0795" approx. And a new set of Mr Gaskets measuring 4.1470" approx.
Block bore is 4.0695" Everything measured with digital verniers.
I think Mr G compressed thickness is .028". I gotta chk to be sure.
Machinist recommended Felpro .042"
Can anyone tell me whats recommended for bore size on head gaskets?
Al also mentioned to leave the plug at the rear main alone. In all his years he installed one and that was because the block came to him without one. So an install was a must.
Also stopped at Dodge store and picked up oil pan gaskets n seals.# P4452097. Seems pretty flimsy so we will see. Only $12 so not much lost if it craps out. After I had ordered this one I saw a reusable one from MP so I may try it.
Not much progress really lol. Next step checking bearing clearances. Try to get to that in the next week.
Thanks all
