Just a quick FYI for anyone looking for something w/ the same basic thickness & combustion chamber diameter & volume as the standard Fel-Pro 8519 PT-1 PermaTorque head gasket, only a bit more heavy duty for higher compression applications. I've finally had a chance to do a side-by-side comparison of the 8519 PT-1 w/ the 17059 "Marine" series head gasket and from what I can tell they are dimensionally identical.

And if the Fel-Pro tech info I've been able to find on their various head gasket types apply to the bb Mopar gaskets as described as for bb Chevy gaskets, the 17059 is constructed the same as their Performance-series gaskets w/ the exception of not having the steel wire in the fire ring. That's fine with me because I don't like how the pre-flattened wire rings still brinell aluminum heads.

What I don't know for sure is what the volume of the 8519 PT-1 or 17059 end up being when compressed. The spec I see for the 17059 says 10.3 cc IIRC, but what I found a long time ago (but can't locate now) for the 8519 PT-1 was more like 10.9 cc. Also, these things must crush quite a bit when torqued down because they're listed as having compressed thicknesses of ~ .040", but two quick measurements I took of them right out of their packages came up more like .048".

Either way, they both have a large enough ID to clear my 4.380" bores w/o excessive gap being left, plus the scallops where they're opened up a bit more for room for the valves just clear the CNC'd chambers of my Victor heads w/o any overhang into the bore.

Good info..I am about to buy a set of gaskets myself.

The Fel Pro " official" specs for the 8519 are 4.505 bore ( careful where you measure), .039 cc compressed, and 11.2 cc volume....carry on...

Where do the 1009's fall in the mix?

I run the Marines on my 440.It has 12.5 domes and the first Stealth heads.They as said list at .039 compressed thickness.Mine have been on 4 years street/strip.No problems.Rocky

From past research my notes indicate the exposed fire ring in the PT was a tin material, and it was stainless steel in the 059 marine.

And because of that I always believed the stainless steel, being harder than tin, would probably do more damage to an aluminum head, and that's why I never used it.

Please correct me if I am wrong on that?

Thanks!

dont know about a bb but I tried there marine gaskets on my 14-1 sb and they did not hold up at all.

Brad these are a WAG but i tend to agree with you're thinking. i do often question the volume specs especially if the gasket appears to have identical dimensions. i don't feel like digging out the felpro catalog right now but am pretty sure the marine gasket has a stainless fire ring and tend to agree (though no direct experience) it's the encased wire on gaskets that impacts the head. i popped a 8519 on my engine and replaced it in kind but always questioned that choice. if i keep the car and end up pulling the engine down i was thinking about using the marine gasket or MLS
