Valve job value??

[davew833]

So I've got the heads off my '92 Pearl to replace the head gaskets. The local dealer talks me into buying the whole engine gasket kit, since it's got all the necessary seals at about the same price as just the head gaskets, valve cover gaskets, and cam seals. (BTW: Dealer was willing to beat Subaruparts.com's price with shipping.) Now since the car wasn't using any oil, I was just going to surface the heads, replace the gaskets, and call it good, but I've got all of these valve stem seals and things and I was wondering if it might be a good idea to get a valve job anyway since the heads are off. The cost of the machine work/seal installation is about $300 extra. My concern is that if do a valve job, my piston rings or bottom end will go out soon after. The engine has 160k miles. Any suggestions?
