Any help will be appreciated.

PM Jeff Colvert on the forum here. I'm sure he could hook you up.

Bill -

Call Johnny Case at Case Machine and ask him. He knows lots of machine shop people around the state. Also, somebody in LR has an Isky tool because the drag boat people used to do that a lot on aluminum head BBCs. Call Leonard at Auto Sports Center 501-375-7223.

It seems the biggest problem comes when a machine shop isn't careful enough to keep the groove depth uniform.

Jeff, the block is already installed in the car. I just want to do rthe head.

You should be able to put a grooves in the block with the Isky GrooveOmatic while the engine is in the car. Vary small radius required and simple to use.

Cutting the head is different from the block,the Isky tool everyone is talking about is for the block ONLY not the head. BHJ makes tool for heads has plate similar to torque plate that bolts to head to locate cutter assm.
You can cut head on boring bar or mill but you have to have a way to center it or locate so you can cut the grooves in the correct place,when you do the block you locate off cylinder bores like you do when you bore cylinders,the head does'nt have a way to locate where to cut.
Someone that is real good on bridgeport w/ dro could map the bore centers w/dowels as reference point then transfer that to head and locate bore centers and cut the grooves,but it would be big job to do that way.

I don't know what kind six you are workin on But if it has same bore centerline as a V-8 someone has plate for to cut receiver grooves then could possibly adapt to use on 6 cyl.

Nope; just looking down the road at the time when I have 25+-pounds of boost and that is a real possibility.

I should have thought about that before the block went into the engine bay...

20/20 hindsight...
