POrted and polished the b16 head this week. Well, didnt really port, just polished the casting and knife edged the dividers. Also installed new valve seals and ITR valve springs. Itr intake cam is going in too, and ill chip the PR3 so ill be shifting at 8400-8600 now. This head is goin on my 96 b18c. Ill post driving impressions once i get it all back together.

its where the runner turns into 2 ports. 1 for each valve. what he means by knife edged dividers is that he grinded where the runner splits to a knife edge thinness. to minimize turbulance, and maximize efficiancy and air flow velocity to achieve higher hp figures.

Re: DIY Port and Polish pics (1hotintegra)
did you use the flow machine to test the flow of each port? My friend is honda mechanic, he said that if it flows uneven, you could damage the head and loss power. Just to let you know, before everyone starts porting their heads.

You took off you GSR head for a DIY ported b16 head and you hope to see 10hp? What about the lower CR because of the b16's bigger chambers?

Re: DIY Port and Polish pics (hot_EH)
The car is a 89 Civic LX, thats right a four door. I posted some pics a couple months ago, heres the link.https://honda-tech.com/zerothread?id=506010 That was the week i did the swap, some stuff has changed. The battery is in the trunk, so the intake can fit, and currently theres no head on there. Im towing the car to Upgrade Engineering where they will install my b16 pistons and put everything back together!!! Ill give driving impressions soon.
