Different Cylinder Heads

[Joey]

I'm replacing a cylinder head on a friends engine. The new cylinder head requires 19mm reach spark plugs. The cylinder head on the other side of the engine takes the 14mm reach plugs. Is this a problem? The valves are the same size on both heads - 35 & 32mm. The engine is a 1600 dual port.

Thanks.

Same volume giving the same compression ratio? If yes, I'd mix and match.

I built an engine with two different sized valves.,,the intakes on one head were larger than the other head..stock configuration and Ill be damned if you could tell..stands to reason that given everything else staying the same,the difference in valve sizes would "equalize" to each other..
