Having an issue determining if these are going to work or not? I bought it through Summit last fall, where in their description it stated it fit all production 302/351w blocks from 1968-2001.

Gaskets went on just fine, heads are torqued on (GT40X) and then just for giggles I decided to Google the part number......
One of the sources I found Fordracingpartsdirect.com (absolutely brutal, rude customer service BTW.....will never buy from them, nor will I recommend anyone else to either) shows in their description that it's designed to fit the FRPP Boss blocks and not the production 302 and that it will not work with the production block???
Seems I stumped the guy at Summit when I asked him which description was correct and the guy at fordracingpartsdirect couldn't even be bothered to have the conversation.
So.....basically from what I've gathered from my reasearch is that you can't run the stock style 302 gaskets on a Boss block because of the additional lower cooling holes in the block. Doing so will result in severe coolant leakage from the rear of the engine. This much was clear to me.....but my question now, is can you run the FRPP Boss style gasket on a production block? Only one of the upper cooling holes exists (left hand side) on the production block and neither of them exist on the bottom, so I can't see it being an issue, but I don't know for sure? Another note of concern for me is the differences in routing of the "print-o-seal" type o-ring design between the two gaskets?
Has anyone else got an answer? I planned on buttoning of the top end of the engine tomorrow, but it looks like I'm at a standstill for now if I'm just going to have to rip it all apart again just to change a gaskets?
Pics to illustrate my point....
Standard Fel-Pro 1011-1 302 Head gasket
Standard 302 block
M-6051-CP331 Head Gasket Note the additional coolant (steam?) holes at the bottom of the gasket....shown at the top of the gasket in the picture.
FRPP "Boss" block
Note the additional coolant passages. One upper right, and two at the lower portion of the block compared to the production 302? In the FRPP catalogue, their only footnote states...
Doesn't really tell you much?

Pre-flattened copper wire combustion ring. Exhaust side is straight to accommodate FRPP block water passages.
