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.

hey guys, I live in a little town where getting results are slim to none,just hoping to get some extra Hp, and this is my first attempt at porting so any gain would be great for me, would love to have a flow bench handy! thanks
looks great, wish I was confident enough to dive into my heads LOL
