cad/cnc head porting

[ereckerdeet]

Several dsm shops use cnc machines(computerized precision cutters which accept a cad drawing) for head porting. I have access to a cnc through work, and am looking for a cad design I might be able to use(wether it be free, or purchasing a one time 'license'). They are freely available for some domestics in a wide range of flavors( i know a plymouth guy who if you send him your valve size and desired flow, he'll send you custom drawing for $50).

Does the DSM community have anything like this?

If not, has anyone had any good experiences with any shops in the midwest, near Indiana? (shipping is expensive, and I'd rather have it done locally if there's anyone here who can do it right)

Thanks!!

I had mine done by Jackson Auto Machine... Excellent job and an all around good price. The machine shop owner, Carmela, can help you with whatever you need. Shipping shouldn't be all that much. They are located in Maryland. I don't think too many places are going to be willing to give out a cad/cnc file. Takes a lot of time and testing to get it right.
