Speedmaster head oiling question.
I'm looking into getting a set of Speedmaster flat tappet heads and I noticed that it mentions "oiling through rod".
My question is would I just run a set of hollow magnum push rods? Also does the raised exhaust port (+.625) effect anything other than header location, like push rod length or rocker geometry.
These would be replacing the stock 72 318 heads on my block. It currently has a 3.9700 bore on a 4" stroke with 9.3:1 cc pistons, and a comp extreme energy 218/224 cam.
Thanks
