I was thinking about porting my 1g head. I dropped it off at the machine shop, and get it back tomorrow. It's getting the bowls and holes enlarged to support 1mm oversized valves, HKS 272/272 cams, crower springs, titanium retainers, hot tanked, etc.
I also spoke with a reliable shop around here for port work, as the machine shop didn't do porting. They said it wasnt really necessary as the head flows so much as it is now (way more than say..an integra head). With all these larger mods and such, I was wondering if I'd need to port to get the full benefit? The shop asked me to drop it off for porting before machining, but they neglected to tell me that when I spoke with them the first time around. They said the porting would mostly just be a lot of work to get rid of small nicks and such, but wouldnt really do so much as for enlarging the runners and such.
What are you suggestions/opinions on porting? Is it something to get a good amount of flow out of, or is it already at a good enough size as it is?
