Im looking for someone who can help me with a company that ports heads. But not just that, polishing, milling, valve jobs, ect. The problem that Im running into is that everyone I call (AMS, Buscher, ect.) has stage heads and dont offer just the work. Does anyone know of anybody that can help?
 
Post up in your local/regional forum ( if not done already ) as someone in the area will know of a competent machine shop ( competent being the key word ).
One in my area does not specialize in DSM's ( SBC ) but when I took a set of newer heads from a Dodge PU they did a ton of research and a beautiful job of P&P and gasket matching.
 
I own a performance shop here in my area and my business partner owns his own machine shop. I've ported several of these heads, and he has machined countless numbers for me. What type of work are you looking for?
 
A very aggressive port and polish job, CNC preferably, 5-angle valve job, milling the head. Basically the baddest head job you can think of without installing any of the parts.
 
There is a lot to building a head then just slapping in parts. The machine shop needs to know what springs and valves you are using so they can check the recomended installed height. They need to see if the guides fit properly with the valves. I would check with Shep about Fox Lake or something like that.
 
Only so much machining can be done to a cylinder head without the parts that will be installed. When I port a cylinder head, the head gets heated up, then the guides knocked out so the transition between the runners and the bowls can be addressed while porting. Once the port work is done the the head is heated up again and the guides are then installed. At this point, the valves are needed so that the stems can be measured, so the guides can be properly honed for clearance. The head then gets resurfaced. After that, the seats can be cut, and again the valves are needed to to check for leakdown. Once all of the seats have been cut, then the valve stems are ground down to spec for the installed height of the valve tips. So, point being, the valves are the only thing that you need to get the machine work done. The springs can be installed later as long as you have the proper tools to install them.:thumb:

He is located in Portland Oregon, and if he doesn't do it he can point you in a right direction for sure.
Give them a buzz, they are very helpfull.
I got my "STAGE 3 cyl. head" done local here in Michigan for cheap. $250 for all labor with my parts including: milling, +1mm valves, bronze guides, bench flow testing, 5 angle valve job, hot tank..etc.. all the works!
