Anyone have the limit specs on the rear main/flywheel flange diameter? I don't see it listed in my service manual. The crank has been ground before and one of the main reasons the engine came out was to fix the rear main seal leak that I haven't been able to solve.

It appears that that flange has also been polished to maybe take out a groove from prior seals. The new seals fit very loose over the flange. So I need to determine if I need to look for a new crank. I'm not interested in using a repair sleeve.

You are talking about the factory aluminum fox valve covers? Since mine is a cobra I have the stamped steel covers and they are a long ways from fitting. Using factory ones would be great since I want to keep the oil fill tube and I don't want to have to run an intake spacer with taller covers.

I'm having a hard time finding a pushrod length that provides a nice narrow pattern on the valve tip. Any recommendations or should I look at buying different rockers?
