I'm buying a Prus high compression head and need to know the pros and cons of the 14mm spark plugs. Opinions? PK
 
My Op is go with the 1/2 openings. You can use the adapters if you want to use 14mm plugs but might find that it is hard to find non resister plugs. If you are running coils the resister plugs don't like the voltage spikes I have found that they don't hold up very well. If you use the 1/2 in original type plugs you might find the car runs better. Others will have different OP but that's mine.
 
With a HC head and 14mm adapters, you'll have a very wide range of spark plugs to choose from to get the car to run just right.
With a low compression (Stock) head, I've found that I can get my cars, to start easier and idle smoother using good old Champion X's.
Cheers,
Rob
