Dom, motor is still on the stand, but I plan to run 3.54 gears and power brakes. I figure I'm pushing the limits even with the .557 cam. I talked to Lunati, they recommended the 60341 or the 60342 on 112 centers. With 1.6 rockers, 60342 would net similar duration and .586/.608 lift, but would the time & expense really yield a significant power increase. The article leads me to believe that the answer is no unless I'm willing to spring for a roller.

Which heads? What do they flow? I would run a 108 lsa myself installed around 104-105 for more down low grunt but that`s just me.
