hey guys. i was wondering what some of you use when porting your heads. all i have is a dremel haha. thanks for the help. pics of you own ports would be good too.

 

dremel works
But only for a little while or you need to have patience or you burn them out

i started out with dermel, they work great for me, but it's hard to find any carbide bits with a long 4-6inch 1/8 shank.. so i went with the big boyz and got me a Air die grinder and a electric die grinder.... Here's a D16y8 head i ported Enjoy!!!

 

i use a dremel, but have a air grinder at work for the initial shaping. these are some of my b16 head intake ports(not finished).

 

nice work guys, i have an air grinder too but i'm still kinda scared to use it since this will be my first time "attempting" to port a head. i'm a SOHC guy myself and i'm about to get started on my p-08 head. i'll put some pics up once i get started. by the way, i thot on the D series head it isn't advisable to touch the floors and knife-edge the dividers on the intake side? i read about this on other forums. any comments? plus i'd like to find out how to make vertical ridges on the intake ports to keep the fuel in suspension. thanks guys.

Endyn does it..

 

From an old post from Bisimoto Ezerioha:

Greetings all,
It is an absolute pleasure to finally see a dedicated page to the mighty d-series motors. I have also been audience to all the comments on my vehicle, and the speculations are pretty interesting and comical to say the least; but I digress. In my vast experience with the d-series engine, whether a full blown n/a race engine or a tame street vehicle, it is wise to only mildly port the head..mostly clean up the bowls and casting ridges. Definitely never take material from the port floor: this kills performance by decreasing port velocity. Even though a common practice, polishing the head should be avoided as well. The intake ports should be kept slightly rough (vertical ridges preferred), in order to keep the fuel in suspension, and not allow it to stick to the port walls. It does not really matter if you polish the exhaust...it will get coated with combustion by products anyway.
An ideal alternative from milling the head is having the combustion chambers welded up on the non-vtec head. Not only does this increase compression, but also increases the quench area: developing an ideal space for proper burn and flame propagation = more, efficient, and less-detonation prone power!
If you need referrals to shops than can help you with these tasks, let me know. I know them all: reputable and cost effective. Note: I keep racing d-series motors because they are relatively inexpensive to build compared to b-series: I hate spending money, and i desire to be fast!"

I can't say Bisi wrote this himself but after reading a lot of articles it makes sense.
