360 roller

Hey guys , My wife recently picked up a 360 roller motor ( 89 casting) at auction ($75) the heads came with it but were off, no pushrods. I am thinking about running it as is with just a timing chain swap and a new oil pump there is almost no ring ridge and I can still see some cross hatching spots on the cylinder walls. the heads are 308 casting and I am thinking about freshening these up. My questions are can I use a regular hydraulic cam/ lifters in this engine? what pushrod type/ length should i use? any thoughts on running this as is? Obviously I know nothing of the history on this motor other than it appears stock. The timing chain does have a good bit of play though. I am on a budget with this one and will probably put it in my 79 power wagon that sees 1000 miles a year.
