retorque heads to solve issue?

One more time for YR...

The manufacturer does not print or state to re torque them. Go look it up.

You can re torque if you want... but consider this....if your gaskets leak... you installed them wrong or had inadequate deck finish to begin with.



To my friend 67, No leaks here.

Best machine, who has an outstanding reputation building Mopar engines, built my 422 W5 motor. They used cometic gaskets.
Motor was 13 to 1, X block
They never mentioned retorque the heads after i got it running, so i never did. Zero failures, beat on it for years, had it freshened, beat on it more.
If people feel the need, do so. But based on my experiences over a really long period of time racing smallblocks, have never re snugged up a head, ever. Maybe i am just lucky
