Found out after I bought my 2nd hand Stainless Marine manifolds, that they were the older style with the water outlet on the slant rather than the flat for the port side manifolds. Well, no worries just had to get a little creative with the oil filter mount. After a few measurements, drew something quick up on CAD and had a friend laser cut some stainless. Now, I just need to bolt them up and make sure they work.

Here's one mounted. Just need to tweak the one oil line and get permanent hardware. And yes, I can get the oil cap off.

I was lucky enough to have a friend working at an Aluminum fab company who made up half a dozen steel offset pieces for my stock oil filter mounts
