"... I ground the head to accept a tapered plug as I usually do so that I can keep all my EI plugs the same. So,I'm gonna have to do some rpm test with different plugs once I get the motor set up more."
This is the first I have heard about regrinding the plug seat for a tapered seat plug. I would like to do this also. Details/tools needed please? Thanks.
