Just signed up! I've got some D3VE A2A's I'm going to port for my turbo build!
1 question though...
Should I have my head shop deck them and do the valve job before I port and polish or should I do all the "machine" work after my "handy" work?
Edit: Also, I will be running a Comp Cams custom grind cam in the mid-to-high .700's with 255-270 duration, Solid roller...
Hit me via telephone or email and i will sort this out for you.
When going to large valves you should have the machine shop rough in the seats so you can port accordingly. You can them take the heads back for final finish.
