Rol gasket question

[Paul G]

I bought a set of Rol gaskets, part # HG31130, from 440 Source along with the Stealth heads. I was doing a little search on here and started to wonder if Rol gaskets are going to work with aluminum heads on an iron block?

ROL gaskets are fine for a mild street/strip application.    I would try a test fit to make sure they clear the chambers without any overhang. 


Here's some excellent info from Fast68 (Porter racing heads) on a potential fitment issue :

I test fit the Rol head gasket on the Stealth head. Like the pics in that link it does overhang just a little in a couple of spots on two of the cylinders. You can just feel it is not flush. I would say no more than .010" if I were to guess. I dug the used Fel Pro FEL8519PT1 head gasket out of the trash can and it had more overhang than the Rol did, and in more places. So I put the heads on with the Rol gaskets and started all the new ARP bolts in the holes. Just left them hand tight so the heads wont fall off.

if you follow that mess carefully you will see that the rol gasket has had the the holes for the dowl elongated to move it down.  the same think was done with a 8519 and made to clear.

Paul, just elongate the dowel holes on the ROL's and adjust the gasket....don't sweat it

Digging up an ancient thread here..

The guy checking my heads called for a gasket to make sure they don't go too far when unshrouding the valves.  I have the  ROL gaskets but was curious what others have used successfully. 

Thanks,

The ROLHG31130HT that 440source sells should work out just fine.
If not there is always the "even larger bore" FelPro-1039, the 1105, or even the 17059 Marine gasket ( a few guys on Moparts have used this one, because it's about 1/2 the price of the others).

Thanks, I'll have him use the ROL gasket unless he finds that it overhangs.
