I was just curious about O-Ringing the heads and block.

I plan to run 12:1 .040 455. It could have anywhere from 550ftTQ-600ftTQ at 3000RPM and shifting at/around 5800RPM. I have yet to pick a Roller CAM. I will be using a stall speed no higher than 3000 to keep some street-ability. 700R4 Trans, Eaton 4:10 (I know too much gear), 69 Firbird Conv.

-First would I even need to O-RING?
-Does the block and heads need to be o-ringed?
-Are there special gaskets needed?
-Is it worth it?
-Pros vs. Cons?

I figured the need for o-ringing was when 14:1 or more compression or NOS was being used. I may be wrong. I run 12.4:1 and eheads but no o-rings. In fact, I had the heads off for 3 months and re used the Fel Pro gaskets and its still going.

Wang whats with all the pictures it a parking lot.....

I agree with Jack. 3 years at 13:1 w/680 HP, and no head gasket problems running Felpro 1016's. Now, if your planning nitrous, that's another story---- Bill

I o-ringed my block at 12:1 with the Butler gaskets, just in case. Having one less head bolt per cylinder than the bowtie crowd makes me nervous.

Chance favors the prepared mind.
