I have ProParts in my 68 Cuda right now with 440-1 heads on a low deck. My engine is also set back a couple of inches and I still have one tube that barely touches with small front tires.

It was such a PIA to get the clutch out I ordered in a set of weld up Headmans and will be spending some of my winter update time fabbing up some new ones.

With a tall deck in the stock location they might fit better, but I HATE having to work on anything near them right now.
