Thanks for your thoughts.

The heads are TrickFlow Twisted Wedge 170s (PN: TFS-51400004).

These have been used on a few SBFs here with no change of pistons.

TrickFlow website also states, “Trick Flow® Twisted Wedge® heads are the only aftermarket heads that can run 2.020 in./1.600 in. valves with stock, unmodified pistons and performance camshafts up to 0.550 in. lift” (Trick Flow® Twisted Wedge® 170 Cylinder Heads for Small Block Ford: TFS-51400004 - trickflow.com)

Regardless, I will heed your advice and check the clearances carefully.

Thanks, I am tending towards doing at least the rings and bearings while the engine is out. Also, every (?) gasket and oil seal will be replaced.

Cheers
