That is a good question and one I wondered about when putting an engine together some time back.
I could swear I read an article or report of some kind stating those large holes were closed off for a reason -- I think it had to do with balancing or forcing more flow around a couple of cylinders -- but darned if I remember where or what it was in. I didn't find it in the usual tech bulletins or SC's. I just looked at some new sets of gaskets and none have holes in that area. One pair I think might be factory, one brand x and two are Felpro. In looking at some old used gaskets I had hanging on the wall, two pair had the gaskets solid so were blocking flow and one set had about 1/4" punctures thru the center of the embossed triangle areas. On that set it appeared as if someone thought there should be flow so stuck an awl thru to open it up. Maybe Jack or Ross will have a definitive answer.

probably no help, but here is the gasket I got from the Max Merrit kit.
some of the holes are blocked.

Hank's and the SM photo are like the ones I have except for the set with the center of embossed area punched out.

Wow!!! It's like the calvary just came over the hill. I really appreciate all the input. To answer some questions, The block vin matches the car vin 5587-4098. As far as I know the car was purchased in CA and it did not have a block heater when I got it. The old gasket had no P/N markings that I could find, the new one is from an engine overhaul gasket set I purchased from Kanter's last year and it has a mfg P/n of Best 719 on the gasket. The engine has been overhauled prior to my purchase. I can tell because the pistons are stamped .030 on top.
