Cat head studs?

There is a company that sells an italian made head that might be worth looking into, though the last person that checked was told that only 12 were initially sent to the states and they havent heard much more about them, I have heard excellent things about their B/C model heads.

One reason that you might have been getting the run around from ARP is that they made the head bolts for one specific person, and I believe he is the only one that they can be bought from.

 

Hello.
Have you done receiver grooves in liners for the stainless steel fire-ring wire which in cylinder head?
Like on this picture

 

Yes, I had them installed in the head. I also filled in the relief cuts between the cylinders. Oh sorry I misread you'd post. No I didn't cut the grove in the liners it isn't needed.

 

That is more involved and requires modification of the head gasket as it does away with the stock fire ring, the process that we mentioned only requires work on the head and is used with the stock gasket and liner.

It is also known that with a factory cat liner machining the groove into it for the wire ring weakens them significantly and leads the the flange cracking.

 

Could you tell me the height of protrusion and diameter of stainless steel O-ring wire, the depth of the grooves in the cylinder head?
I guess 0.041" wire, and groove depth of 0.035" (0.006 above deck)?

 

All I know is the ring protrudes .005 from the head.

 

LoL, why would he give proprietary information out for a service he paid for?

The tub of material alone for filling the relief cuts is $500, they charge around $1000 to do all and their machine shop has the jig already made to ensure it is done properly each time.

 

Best grand I ever spent on the engine!

 

So can you say who is they or them that has done that for you? Never saw that done on a big cat.

 

Im sure he would pass the information along to an interested party in a PM, as would I, but for someone just wanting information on how to do it their selves I will not give out that information.
