I'm not 100% sure but I'd be surprised if it wasn't the 8519. Just miked one at .048"

For any "performance" application, the BB wants/prefers the 1009 o-ringed gaskets which also has the SS armor wrapped around the internal o-ring. The 8519 is simply a RV/truck gasket with the additional 2-cooling hooles per spark plug area... and those only work IF the heads and block have thos holes cast into them. The set ou showed in your photo is the Federal-Mogul "SEALED POWER" KS set... it does not have the performance gaskets included.

Guys, let's step back a minute and ask "why?".
Why bother with all sorts of guesses and ideas when the OP can very easily CALL MANCINI and get the answer. No guessing involved!
Also, for 90% of all the bigblocks built, the 8519PT is sufficient gasket. Now if it hangs over the chamfer or otherwise into the bore, it won't work. But saying it isn't acceptable unless it has "armor" over the crush ring is just malarkey.
People on this board have run those supposedly inferior gaskets up to 11.5:1 compression without trouble.
Shoot, if you want to spend money on a gasket, get Cometics. At least they are reusable!

I'm doing a BB build for a guy (1st one in decades) & cant believe how restricted the coolling holes are on the 8519PT, the 3 slots at the top ain't going to cut it & very little openings on the outer edge. Cant drill em, I tried on the center piece that overhands into the valley just to see. The HF hole punches wont go thru the metal core. I'm going to a machine shop tomorrow & see what they have for a punch. Dog you got any info/tips/suggestions for me

The intent of those slots is not coolant flow, it prevents air pockets getting trapped.... The intended coolant flow path is front to back around the heads the down around the rear cylinder & toward the front.... By opening the coolant passages mid way you allow the coolant to bypass the rear cylinders...

When I read issues of gasketing, I take special interest because I had worked for a major gasket company and I know how gaskets are designed, as well as per applications, typical cataloging and marketing.
Head gaskets are designed, with respect of coolnat flow and control, to be restrictors and directors of the coolant flow pattern and volume. IF you choose to alter them away from your cataloged aplication, you run the risk of trouble with coolant control -- for any head gasket application of any make/manufacturer, etc.
The additional coolant holes on the 8519 BB head gskt are for spark plug area coolant purposes so to help prevent hot-spots causing detonation under such service loads of operation (truck/RV). The cooling holes match the OE-determined design which also matches those specific castings (head and block having those extra cooling passages).
If in doubt, call the MANUFACTURER'S Tech Line yourself for the best direct answer.
