Im about to use a 2.8 bottom end with a N/V 2.5 head

Will probably rebuild the crank and rods into a 2.5 N/V block though as ive heard the liners move about in the 2.8 and cause the head gasket to fail.

N/V inlet cam has 1mm higher lobes, the valves protrude past the head face so should mean higher compression, also has double valve springs winkeye

Anyone know if there are any oversize pistons I could use?
May aswell while its all in bits eh :)
