high c/r ls/vtec what plugs do you suggest?
 

ok just built this high compresstion ls/vtec with a completly forged bottom end wiesco pistons and scat rods. only problem is that the pistons are so domed that they hit the spark plugs and almoost crush the eletrode. anybody know what plugs would be more resessed in the head or plug that wouldn't hit. part numbers are welcome thanks
