CF- You a small block Mopar?- If so no need to remove the distributor-it's outside the Manifold.
Just did my 318 with a performer and 500cfm. Little coolant did leak from mine @ high RPMs (outside of block-none in oil) until it warmed up and the gasket swelled. After it cooled down I tightend the bolts once more and no other problems.
The carb was damn close outta the box.
