Hang on friend;
This is waaaaaaaay beyond the OP.
And certainly not something to put thousands of miles a year on. That engine is, IMO, nothing but bragging rights.
"The brain of the engine was a COMP solid flat-tappet camshaft with 247/247 degrees of duration at .050-inch lift. A mix of Harland Sharp and Crane rocker arms (1.7 intake and 1.6 exhaust, respectively) brought the lift to an impressive .622/.597 inches. The R/T Magnum heads were designed as basically an upgrade to the later-style Magnum heads, and the nonadjustable pedestal mount rockers wouldn't cut it with an aggressive solid lifter cam. A Crane rocker stud adapter kit was used that also incorporates a set of built-in pushrod guideplates. The kit goes a long way toward improving the valvetrain on the R/T heads, but with the 5/16-18 threaded holes that the studs live in, there is not a whole lot of stability there. Being a machinist, Adney solved this dilemma by making his own stud girdle."
