What size is the stock ls1 head spark plug thread size? I need to buy a tap i have cross threaded the top 2 or 3 threads on my spark plug head and want to tap it from the combustion chamber out to repair the threads but I am unsure of the size. I believe it is 14x1.25 but want to verify.
Thanks
Dave
