Ashland is just about 20mins or so North of Richmond...no biggie. I dont know of anyone actually IN Ashland that i would let touch any of my heads...but you could hit the Hanover Air Park and get a load of machine shops that would be willing to take your $$$ and probably do some nice work on your head. Try that first. If not then hit up Ballos Precision Machine in Lakeside right off Staples Mill (Rt. 33) and i know he'll do good work. You can also hit the Southside and get some nice machine work done there as well.
Wait for the Southside guys and some more DSM guys to respond and maybe the'll have exactly what you want...i cant really help ya.

PS...being that im in Ashland...what do you drive? You might see me around in a bone stock black 88 Mustang GT or "coming soon" in a 92 SE-R (red) with Rota Slipstreams.
