Heads arrived today - pics/specs/flow numbers
Sent my 317's out a couple weeks back to get ported by a member on the board here. They arrived today and of course I had to take a couple pictures . The heads will be going on tomorrow and hopefully it will be back up and running by Thursday. Here's the rundown of what it got:
Intake valve: 2.08 Ferrea 6000 with 28* back cut
Exhaust valve: 1.60 Ferrea 6000
Intake port work: Stage 3 with upgraded intake seat, hand blended high lift valve job
Exhaust port work: Stage 2, width to accommodate 1 3/4" header
Flow numbers on super flow 600 with flocom at 28":
Valve Lift Intake CFM Exhaust CFM*
0.200 142 115
0.300 211 151
0.400 254 178
0.500 295 200
0.600 322 219
0.700 325 222
*The exhaust numbers are without a pipe.
Just thought I would share with you all. I can't wait to get it running and get some new dyno numbers

Good luck getting back and running. No doubt you are anxious from having the car down for a month. Let us know how she drives.............oh yeah you dont even have to wait for spring break in, so let her rip when she gets good and warm.

I may or not be able to monitor A/F depending on whether I get my gauge in or not, but do you think it would be alright to rip this thing out without a tune? I have a custom tune already for my other mods, but I just want to make sure I'm not gonna F anything up.

Yeah the a/f lower in the rpm range being off a point or two isnt going to kill anything. The higher rpm a/f should not change very much at all. If your O2 sensors are doing their job anyways.
