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.
