Well i am looking to get maximum performance that i can get out of these housings, they are the 12a housings, and i was told and from reading a large amount of porting books post ect, that i should round off the closing edge of the intake port. also the exhaust runner(is that even what its called?) is also quite small) would this improve power by opening this up? The car will not be running any indurance races or anything, so i was thinking a bit more agressive port might be nicer
