Tony W. in post #7 you talked about the difficulty of finding TDC because of the offset of the crank. It seems that what you do is put pistons #2 and #3, exactly the same distance (up or down) their bores and you are right on TDC, #1. (and for no reason that is important here,#4 cyl. happens to be at BDC) (from page 204 of Pages book, Ford V8 Cars and Trucks 1952) A very good old book.
This just saves you having to work out the 1.5 degrees on the pulley.
I have made a bracket that straddles the two lower timing cover bolts from light angle iron. Unfortunately I did this without reading your post #7, and will have to revisit the marking of TDC.

Fortunately I have not yet fitted the heads.
