O-Ring BBF Block For Nitrous

Thoughts on installing O-Rings in the BBF block (10-bolt) for Nitrous application, at least 1 DP kit +?, is it worth it on the BBF and if so any recommendations.

This is just my op but a set of mls gaskets will do just fine

Thanks M, I agree I have pushed the small blocks but I hate having the head gaskets ventilate and need to remove and deck, especially if I go with an aftermarket block, the two I have here will probably burn up LOL ...I want to build a third BBF having never running any of them.

just cometics here with 500 plus of spray ..... no water in the overflow ever

had an o-ring block with copper gaskets , nothing but problems ...... went to a cometic with a smooth ra and never had an issue

And dont kill it with timing.

I was a little surprised that the o-ring process consists of file fitting copper or stainless wire, as opposed to having a 360* (not 358*-359*) CNC'd or water jetted ring tapered and driven in...maybe something to look into

I resemble that comment Lol...been there done that, used the old old school methods to compensate and burned up some stuff I think a 7531 will be in order, I tend to start with less timing and creep up on it now.

O-rings and copper gaskets work well together if you don't run water! Lol....

You mean your supposed to run water with this kind of stuff

You can run water, you just drain it once done playing. 7 PSI cap helps cut down on the leaking too. Ive got stainless steel insert ring in the block, .033" thick copper gasket from SCE and receiver groves in the heads. All water passages had a .030 or so RTV smear that had all but set up before the head was set on the block.
