Peeps,
what are the advantages or disadvantages of using a 2wd bottom end (205 Block) with a 4x4 cylinder head..?
does this require any machining work on the pistons.. or should both fit together without any problems..?

situation.. I've got a 2wd engine with bent valves only (block and pistons are good) and I've got a spare 4x4 head in good condition, new tappets etc.
