Brownfield heads, "60/40" offset, and roller rockers without needles. Help!
My 68 El Camino is biased toward the GT/Road Race end of the spectrum and will never see a drag strip. I intend to drive this car a lot. Cam basic operating range 3000-6900.
It seems my Brownfield heads have a 60/40 offset just like the early AFR 120's.
From what I have been able to find out the early AFR 120's are Brownfield with a name change.
Lots of discussion on-line about poor valve train geometry with the 60/40 modification.
But they have been on the market for decades so I would expect this to have been sorted out by now.
Building a wild 327 (333") and have put a lot into the bottom end.
Heads were a "Deal" that maybe was not, if I have to go to shaft rockers.
Not a fan of needle bearings or aluminum rocker bodies.
Tried looking up various companies to determine who may have what I would like.
Not having a lot of luck with this.
Seems nearly everyone uses needles and aluminum.
Comp Cams might work but reviews on them are mixed.
Suggestions please.
At these prices I want my gas 100 octane, leaded, and my windshield washed!
