Have a question about push rod tubes..I'm trying to get a 71 back together to sell. The original head had poorly done helicoils in the plug holes, so I got a replacement (9 bolt), but the 71 push rod tubes appear too long. Both being 9 bolts, I am under the impression that there are 2 options, long and short tubes (short '63-68, long 69-72) Correct? Push rods the same for both? Thanks.

can't remember off the top of my head but you are looking for approx' 0.040" (?) gap between head and gasket when all just sitting and waiting for head bolts to be torqued down.
Yes there are different square sectioned tube rings and thickness head gaskets.
The answers are all here on JJ search Mr Pete , Tony the Torch and Wes White (four aces wes ?) try to get hold of Wes' motor build dvd he probably gives the answer there.
