cast iron high rise dual plane sbc

I have a 72 chev p-u. It has a 355, flat top four valve relief,s forged pistons. 194 camel hump heads. hei. headers, holley 650 vac sec. It has a cast iron high rise dual plane, with a bow-tie emblem bhind the carb. I think its off a boat. i seen one on craiglist, it said it was off a boat. Is this a good intake for my combo. i have a 87 later performer dual plane, can it be used if i redrill the 2 center bolt holes, my brother said it may work. will it, and will it help my combo? oh yea It has a very lumpy solid lifter cam, dont know the specs. but it is pretty big judging from the sound at idle.

The issue will be getting the underside of the bolt heads to sit tight on the manifold. A little grinding on the manifold should solve this problem.
