Yes, I have oe rods. What do you call "exotic" head work? Porting? I would guess no more than around 450 or so lift with te stock head. Like that biggest Comp solid grind. But they suck.

Porting has nothing to do with lift & I don't consider that exotic.

Why are you quoting stock head lift?

I'm willing to spend $$ for run of the mill machine work to increase lift capabilities.

I'm talking about aftermarket springs/retainers, possibly cutting the seats for the botton retianers.

None of that would be exotic.

I don't want to spend big $$$$ on longer stemmed valves, special rocker arms or such.

For some reason you don't seem to be taking me seriously or you assume I am not knowledhgable W/modified engines.
