Predator-Z ported 317s for his boosted engine Just got em back from the machine shop being pressure checked/machined/assembled with his springs and stock valves. Lookin forward to gettin em shipped off monday 
Wow that looks great! I have a set of stock 317s laying aorund with upgraded springs. What would it cost to send em to you and have the same work done and reassembled and sent back to me? This would be for my D1SC blown 370.

yummy,
They look sweet Bo, they will make some good power on the C6 (8>10 psi) stock cam, with a maggie puffer.
This is not an all you can be motor, but a nice reliable 6.0 that will dish out a comfy 480>500 rwhp.
Thanks again for the beautiful work and all your time spent BO.

I usually take the ramp out anyway except on the larger LS6 style ports on 243s and 317s but on a supercharger application I wouldnt worry about it. Hardly any of the aftermarket heads have it.

That could explain the crappy BSFC numbers I frequently see out of alot of heads.
