302 head gasket installation

Just double checking that I'm doing this right. The 302 Ford block has water jacket holes in the front of the block (and head) but the head gasket does not have corresponding holes. (see pictures below). Is that the correct installation...to block off the front water jacket passages to the head? My understanding is this forces the water to the rear of the block where it enters the head.

Yes it does block off the front water ports. This is to force the coolant to the rear, to aid in not overheating the block, and heads.

I can't count how many I have torn apart a DIY had put together.

Confirming CARSAVVYCOOK as this is big time important. Coolant moves thru the cylinder block, comes up the rear to enter the head, moves forward thru the head to return. Reversing the gasket would allow cold coolant entering from the pump to have a direct path back to the radiator without bothering to cool anything beyond cylinders 1 and 5 on a Ford or 1 and 2 on a Chevy. This means that one head gasket will set upside down.

Yes, that got me a little confused as well. On one bank the gasket goes on with the textured surface and blue markings (as shown in the picture) up and on the other bank the blue markings are down and the coated gray surface is on the up side. Strange.

Anyway, thanks for the confirmation on this guys.
