W7 INFO
Ok, because I suck out loud, I finally got around to taking pictures of this stuff. You can see how much stiffer the W7 head is across the top of the ports where the rocker hold downs are. On the W5, when using a Jesel or T&D system I've had to take as much as .185 off the head to get the shafts in the correct location. If you ported the intakes UP like you should, things get VERY thin up there, not only in the spring pockets but also where the rocker stand blends into the head. It can get messy right quick.
I forget how much I love the W7 head every time I see it. I don't love the exhaust port, but I don't hat it either. I think a 2.200 intake valve with a 50 degree seat and a 1.600 exhaust with a 55 will be a killer deal. Maybe a 55 on the intake if you can get it in there.
