Machine Shop, O Ring head

[FattyBoomBatty]

If I recall correctly, I had it done for either 20 or 25 per hole, but it was done to my block. I might be able to dig up a receipt, but you maybe can call the shop I used. It's the Carquest machine shop in Hopkins 952 935 0120, ask for Joe.

So all this talk about ringing the head or block... what do you use for the ring then?

stainless or copper wire. I am planning to use stainless wire with a cheapo composite head gasket.

That's what I did. Stainless steel "safety" wire. Then a regular gasket. But I surpassed my old boost level (by one psi) and it held together, so in my mind it works. The true test will be 30psi. Also, I think it would be better to o-ring the block since it's probably easier to get the groove centered on the bore. With a head, the bore centers might be slightly different than the block or inconsistent from hole to hole.

I run 35+ psi with a Fel Pro Permatorque and Arp L19's. Unless you are running crazy ass cylinder pressure, you dont need to o-ring your block.

Proper preparation is the main key, make sure your block and head are straight and your good to go.

$200 head gasket, no

[Super Bleeder!!]

Brads car runs 30 something psi plus a 100shot with the permatorque and L19s. At least i think that what he has.

Well you have to play to play sometimes....

$200 head gasket, no

Plus you missed the fact I said.....

Preperation is key!


I see diesels everyday at work that run 30+ psi of boost with 18:1 compression, and they have composite head gaskets!

I run a cometic HP and A1's..no issues, not even under boost like most dsm's do on the dyno.
