Does any one know if the blocks were machined different for the 90 degree oil filter adapter vs. the straight on filter? The reason I was asking I am trying to relocate the filter on the 36 Plymouth. The center hub that accepts the bolt for the adapter stands about 1/4 of an inch higher than the gasket seat. I looked at 15 different small blocks without the 90 degree adapter and the center hub is a little lower than the gasket seat.

I had my doubts as well. Read my edit to the previous post. Thanks!

Surely someone out there has gone from a 90 degree oil filter adapter to a straight on filter. The engine is from a 71 Challenger, if that matters. Tried several filter plates from other small blocks. I would have to use three gaskets to fill up the space between the plate and the block! Any help?

I gone from 90% adapter to a straight on filter before and never had any problems. This maybe a stupid question, but are you getting the plate on the right way? It should be a straight forward swap. Put your plate gasket between the plate and block, then screw the threaded adapter on to hold the plate to the block, and screw on the filter. Make sure the plate has the raised center ring facing out, so the filter seals on it. I've never seen any block that was machined different in that area. 
I'm wondering if the gasket for the center bolt is stuck on the block or can the plate go one either way and he is putting it on backward ?

Thanks for the replies. One of the first thing I checked was for the gasket left on the center hub. The other small blocks I checked had the center hub and the outer gasket surface almost dead even, the filter plate is flat across the center and the outside gasket. The block I have has the center hub raised about 1/4 of an inch above the outside gasket. I have put the 90 adapter back on with all new gaskets, no problems. Very tight location in the 36 frame. Thanks again.

you're a hot rodder , whip up ring the thickness needed and use a gasket on either side , would that fix it ?
