I received Jim's roller rockers and can only add to the list of others that
have praised his prep and installation manual.
I needed to replace my rocker shaft as it was scored on three rockers,
cylinders 2 and 3, which delayed me over the weekend. I couldn't see the
wear before I removed the shaft.
I like em!! I've always erred on the side of loose on valve adjustment
after burning a valve out in a 441 many years ago but these seem quieter in
spite of me.
On the performance side, at 3500 rpm and up there's difference! I obviously
don't have any dyno numbers but the engine revs quicker and faster. I've
got power I didn't have before!
Pure and simple I like it!! A Lot!!!
