I would suggest draining oil and inspecting it for debris, possibly even cutting the oil filter if you don't see anything real obvious in the oil.  I would do that prior to running with any other gauge to try and prevent further damage if it's already hurt, may cost less to fix.

Where at in Ohio?

Anyway, Dave will probably know more than me, but the 502, mounts and all should drop right in. I think the only differences between the MK 4, and Gen 5/6 engines is internal and maybe valve covers.

It should drop right in....also it is a non adj. valve train...and flywheel/flexplate and dampner is different.  ;D
