Heads for magnum

@DrEamer -


I also did a quick search on the Edelbrock & Trick Flow heads. With the trick flows, this is also stated for the rockers & magnum heads:

“Magnum engines must use Harland Sharp S72025K (1.5 ratio) or S72026K (1.6 ratio) shaft mount roller rocker arms for proper oiling.”

(IDK anything about that and what can actually be used or not.)

When it comes to using the Trick Flows on a Magnum engine, the rocker arms that I mentioned will provide proper oiling. I confirmed this with Mike at B3 Racing, and I believe Brian at IMM also stated it. Just for further reference, a set of PRW 1.6 shaft rockers with Mikes correction kit is $590. The only reason I know is I just bought them, and a set of TF heads from him yesterday. A setup of PRWs without Mike's kit can be had for around $450. Now, like you said, time to break out a calculator!!!
