Hey gang. I'm new to the mitsubishi world. Just bought an 88 Dodge Raider. It needs a new head.

Looks like a valve guide had come loose and danced around for a while, wollering out the hole. It has the jet valves and hydraulic lifters.

I'm looking at the new complete heads on ebay (https://ebay.us/9uvyKz) and amazon that can be had for $400ish (no jet/mechanical lash adj)

There's a warning that concerns me though: "this cylinder head only fits RWD, and it does not fit in FWD." What is the difference? Can I use this on my 4X4 raider?

Any help is greatly appreciated.
