My advice to my coworker was to spend as much of his budget he could on valvetrain. Can't go wrong with spending extra there.
True. But the factory valvetrain is very well designed. 80 gram valves, beehive springs, light stiff rocker arms, short pushrods. When you change one thing drastically in there it sends you down a slippery slope.
Solid roller= more valve spring pressure, small valve spring pockets=very expensive solid roller springs=very expensive solid roller lifters=stock rockers no longer adequate=very expensive shaft rockers=now questionable stock valves=maybe I should have upgraded crank and rods
. It just doesn't stop.
I will just have to see where this ends up, then go from there. It's creative freedom, like mentioned in the pro vs hobbyist thread here on ST.
It's all just self-imposed limitations on my part.
