possible power gains from milling the head?

[blowerbike]

you mill the head or change base or head gasket(lower the head) and one lobe center gets larger and the other gets smaller.
so i thought my post helped explain it.(the question after the fact about cam timing).
as far as milling the head for added power......waste of time and money....

milling the head good or bad???????????????

hi guys i wouldn,t mill the head ,,,, because of the gains you might get,,, i,ve done alot of porting for perfectune which was when they first got their cnc machines i learnt alot from them as well as enjoying it,,, you could open upthe ports and triple cut the valves and do alot of mirror polishing which wouldn,t cost much just alot of work ,,, you would be pleasantly surprised and happy with the results regards oldgrumpy

OK, any sugestions on where to start opening the ports, or where i might find some direction?
