I'm putting a F1A on my LS2 out of a 06 TBSS in a 71 Nova. I bought a 06 GTO water pump so i could put a LS6 intake on it. The problem, the water pump hits the timing cover and has about a .0050-.0070" gap between it and the block. Is there different covers? If so, what do i need?

If it looks like this:

You'll need to replace it with one that looks like this:

Thanks for the time Russ. It looks like the bottom one. I wonder if it's hitting 2 of the bolt heads instead. I could pull them and see, but there would only be a few thousandths gap between the cover and back of the pump.

Does anyone know if that is the only 2 cover designs?

Are you checking this clearance with the pump gaskets in place? They are metal with rubber seals and are close to 0.100" thick...
