Headgaskets

Many good advises here. Thanks alot !! This community is great. I think I will dig in to the Straigthening process. But that deckplate have to be quite thick to withstand the warped head, I think ? Is the article from POCA visible somewhere online ? I'm not a member Roll Eyes

We have a special owen on my job, that I can use. I have used it for wrinkle paint before. It can easily be turned up to 450 degrees F. So all I have to do is make me a deckplate and torque my head down to it.

If the oven was large enough to fit a block. Could not the head just be bolted onto an engine?!
Can't imagine a torque plate being stronger than torquing the warped head to a Cleveland block...Mark

I used the Edelbrock heads and their installation instructions stated:

"ALL ENGINES - A re-torque is recommended after initial start-up and
cool-down (allow 2-3 hours for adequate cooling)."

I checked mine and only got 2 or 3 bolts to move ever so slightly.

FWIW, I re-torqued my Edelbrock heads (ARP bolts) after the first week of running the new engine and got NO movement. All bolts were still at perfect torque.

Rocketship, sure you could use a block, but unless its first verified to be flat, it could create more warpage problems than what you have now. Used blocks are routinely out-of-plane both lengthwise and crosswise, and overheating them causes even more movement, so most shops true up blocks before using them in performance builds. A steel or aluminum deck-plate on the other hand is a shop tool and normally doesn't see engine heat or vibration.
