do you know if there is an easy way to see if there is any bent valves? other than taking the heads off.

Put a new chain, gears, and tensioner on it and check compression.

You can probably get the gears, chain, and gaskets from ZZP for a decent price, although I have heard some quality ussues with rollmaster double rollers recently.
