Generation IV External Engine - porting 799 heads, thoughts please
07-14-2012, 10:21 PM
hey guys im in the process of matching my 799 heads to my intake, Ill add some pics so you can see what im doing, question is I got my intake ported and now I want to port the heads, but the size of the ports in the intake is a little higher than the heads, I can look inside the intake with a small mirror and see that the air flow will be restricted greatly on the head side of things, you can see from the blue ink what a difference it is, should I blend the heads to match? or will I make the head to thin? you can see from the pics where I got a mirror showing the inside of the port, any info would be great.
363537.....head showing how much material I need to remove
363538.....mirror inside intake
363539......another inside intake

well got the exhaust ports done on one head, come out nice for the first try, takes a lot of work! but in the end I think it will be worth it, intake next!

A lot of guys might be holding out because it is proprietary information and how they make a living.
I think you would have better luck on the bullet with something like this.

well Im almost done with the exhaust ports! I went by what some other people have done with there port jobs on here mainly redtail2426, thanks for the input and results, It sure takes a lot of work! now I understand why people charge what they do, the only reason I did my own was because the machine companies around here dont have a flo bench, so I dont see where they could make up the real difference? and they told me to do my own! go figure, anyway here are a few more pics.
