Picked up a set of Mr. Gasket ultra-seal intake gaskets today. I noticed that the gaskets are solid where the smaller center ports are located. Only have the bolts holes there. Will these work?

The packaging states for 1987-1995 Gen I SBC.

Application heads:

14101083...1987-up...350..........Gen.I, also used on crate motors, 285 or 300 hp, 64cc chambers, 72' center manifold bolt angles. (Mortec.com)
