to be honest - calculating length is a MAJOR pita

ive just started reworking my theory using a new engine analyser bit of software. and im getting slightly different numbers.

and be damned if i can crack 100hp/L (just) !!! No No No
100nm/L on the other hand was easy enough.

and for those interested, i had a look at the port orientations in the stock 2jzge head. its actually quite steep. unfortunately the port shape is modified at about 10mm from the head surface (brown looking in the pic) in order to correctly align with the horizontal manifold runners. if you ignore (read 'die grind') this section, the overall port orientation can be seen to follow the rod (which for the best part is sitting FLAT on the floor of the port):
