Cylinder heads before and after
This is my second set of cylinder heads rebuild by
JB Racing in Tavares, Florida. They have all the necessary tools and know how. Price was $ 1400.- with new guides, seals, some new studs and all the labor. Blasted and all.

May just be the resolution of the pictures, but was the head to cylinder mating surface machined or just bead blasted?
Cheers

 OP, I'd take the heads back and have the surface machined. If I'm not mistaken, that is a tapered cut.

Cylinderheads
Early cylinders had gaskets to form a seal.
The lip is only to center the cylinders on the heads.

Craig.
There’s a vicious rumor going around that you may be contemplating retirement. While I’d be happy for you, if you are could you delay it for a few months. I have a 3.0 I was going to send for machining and afterwards a 2.7. Fun fun!! Thanks Tony |

As long as my health holds up which it should I will keep working a long time. I am 60, I kind of promised my daytime employer 8 years plus a lot of my equipment is here. Its actually kind of nice I keep their machines running and I get a nice shop, plus health coverage then I slide in the head work etc.

Plus plus plus for Jim and the folks at JB Racing. They did a phenomenal job of machining for a 3.4 I am building.
Pricing is very fair and Jim is extremely knowledgeable and informative. |
