Allright guys,
I'm in the process of learning to port and polish d series honda heads. Except I don't have any extra heads laying around to practice on . So, If you have ANY head you could donate, I'd REALLY appreciate it. The only requirment is it has to be an i-4. It could be bare, dropped a valve, ANY condition, as long as the area around the ports are in good condition. I'd be willing to to pay shipping, and i'd ALSO be willing to port your d head if you pay for shipping both ways (for the head you want ported). I'm only porting the exhaust side a bit, and polishing the intake and exhaust.
Thanks guys!
Nick
P.S. I'm located in KY.

 

you pay shipping plus $5 and I'll send you a 4th gen head off a d15b2... should be about $25 total....

 

Are you gonna be using a special technique, flow bench, or something else? I've cleaned up some ports before, but as far as "porting" I'd like to know how your gonna be going about it. Are you in a class or just learing on your own. This is scientific stuff from what I hear.

 

Just get a bit for each port, set the speed and count your time in each port to get it even... remember bigger is better.

I count to 100 with a high speed cutting but with a IR die grinder at 100psi.... 120 seconds will go into the water jacket, requiring some JB weld....
















I'm kidding, keep in mind that it's easier to lose power by home porting jobs than to gain
