TBI Adapter bolt interference?

I am swapping intakes. I got the Edelbrock 2104 and a Transdapt TBI adapter plate. I was mocking it up tonight when I realized what may be a big problem. Two of the three throttle body bolt holes are blocked by the edge of the intake.

Could I just use washers to space the bolts so that they don't threat all the way through the plate?

Those factory 454 adaptors are restrictive, plus they rob hood clearence.
Yeah, make studs or assemble the tbi to the adaptor (w/ gasket), & shave the remaining bolt that is sticking out of the bottom.
