Take a compression check first, then have head gaskets checked, may be coolant leaking causeing problems if heads are pulled off then have valve seals replaced at same time.

Hey just did the compression test. Only one cylinder has dry test 60 psi and wet was 70 psi so what's causing the problem piston gaskets or vavles.

Cold be either, as the wet test didn't improve it much i'd go for a bent/burnt valve myself butyou'll see once the head is off.
