Has anyone run the pro comp aluminum rec.port heads yet?I just ordered a pair and I was wondering if anyone has tried them yet and whether they flowed very good?thanks for the input.

I have a set, and you will need to do alot of grinding to get them to fit a stock rec port intake. I also had to have a piloted drill bit ground to drill the guides out enough on my seat and guide machine to get a guide reamer to work in them. let me know if you need any help with yours. I am still finishing up the port matching and bowl blend on my set and will have some flow numbers in a few weeks and some track results in a couple of months.

Here is a thread from another site where we were talking about them, and I posted some pics of mine. My screen name on that site is WSM9808 and I posted a couple of pics of the odd size intake port. http://www.hotboat.net/forums/showthread.php?t=102902
