Nova racing cooling head, plug fitting??
I purchased the nova race pro head for my hyper 8 port. I noticed that when I put the glow plug in place it does not sit flush with the top of the comustion chamber, it's sitting about 1mm up into the threads. I use the mcoy #8 plug and it does sit flush in the stock head. I need to know if this is going to hurt engine performance and if there is anything I can do to fix it, if need be. I live in a fairly small town and I can't find a machine shop to do work that small and precise. Your help would be appriciated, Thanks.
