I am attempting to put the valve covers on my new rebuilt 312 Y block.I ordered new gaskets and when I went to put them on I found that the studs were too short.
After doing some research I found that there are two size studs for the Y Block motors,one for the steel valve covers and one aluminum fined valve covers.
I have the aluminum ones ,so I ordered the ones for them.
I received them today and they are the same size as the ones I have.
With the cork gasket on the valve covers,when I put the rubber bushing on the stud,the top of the stud is even with the top of the bushing. I cannot put the chrome washer nor the chrome acorn nut on the stud.
Any suggestions ?
