Many thanks for the kind words. This one (as well as each one of our builds) is treated very special. The guys here at the shop and the PY forum members challenge me to continue to strive for perfection. Greg has been very kind and patient as this one has progressed. We are thankful and very humbled to be working on at this point, 3 numbers matching 1972 455 HOs along with two other very nice hot rod builds. For the head porters: Head flow volume came in very quickly and never backed up all the way to .900" valve lift. We are expecting near 400HP with the stock exhaust manifolds with this one. The only real change from assembly line stock is balance (with stick flywheel), clearances, cam timing and valve seat work including hardened exhaust seats. Cam timing is our version of the famed RA IV and we are using 1.65 stamped rockers. If we make much more power the stock fuel system will have a hard time supplying the fuel at WOT. :-)
On the intake gaskets, we took a Mr Gasket 503 gasket and did a little trimming and fabbing around the crossover opening. These have the correct intake port opening height.
Also attached is a pic of almost two full sets of 1972 HO head bolts as delivered to us along with a current reproduction bolt set. Since all these belong to Greg we found the nicest originals and used them in this build. Call me silly but I just like the originals better.
Looking forward to the dyno session.
