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.

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.
