does anybody have (or know of a place i can get) cross sections of an l-series head? i'm wondering for porting purposes.. i've seen an illustration before, but i can't remember where i saw it.

p.s. when people say that pulling the exhaust liners out of late-model heads is a PITA, they aren't kidding!

I have a P79 that you can buy and do what ever you want with it.

^^i already have a P79 and an N47.... if we were talking P90 then i might be game...
