90 350 with gen 1 heads?

Hey guys, got a quick question. I have a complete running 350 out of a 90 suburban. I want to use it as a temp engine in my 68 camaro untill i gt the funds together to finish my 383. Question is can i use my heads 292's on it with no problems. I know i cant use my intake on with the heads that are on the 90 350 cause the bolt pattern is different. I dont want to drop a couple hundred $ into a manifold for temperary use. So i wanna use the 90 350 with my 292's and edelbrock intake setup from my 383 for now till i ge the 383 finished. So are the first gen heads compatible with the 2nd gen block.
Thanks guys for the help. :)

The bolt pattern is not different for the manifold bolts on the '90 heads. '96 is when the change took place with the vortec 350.

If the bolt patterens are the same why do all the aftermarket intake's say there for 55-86 engines not 55-95? Are the 87-95 heads different than the 55-86 heads when it comes to mounting the intake?
