360 head trip

I'm porting the same head as Justin, and was determined to cut in a 2.02 valve.

The 2.02 changes the hole characteristic of the port. above 250-260 cfm the air flow quality go to hell in a hand basket!!!

Been porting on these head for 2 years now................still not happy with them.

If your going bigger, go with a 1.94 Valve, it give you room to port with out finding water and creating turbulence!!!!!

O and the only thing a flow bench does for you..........IS KEEP YOU UP ALL NIGHT, TRYING TO MAKE IT WORK FOR YOU:D

Yes indeed, but the wife makes me stop since I set it up in the spare/band room for easy access..LOL

I've been able to get over 270 cfm out of my 2.02 j heads, It does take widening the runner and raising the roof to keep the air speed in check.
At the point Im at now with the J's, it would take going into/through the push rod wall and raising the roof even more to lower fps to flow more beyond .530-.550
What port volume do you have again?
My J's are at 186cc, just give an idea of how much bigger they had to get.
