Update. Changed plugs to the above NGK's and removed Silver bushing for the Black bushing. Replaced one light silver spring with one light blue. Set total timing to 35 and have about 17 intial. Huge difference! I get no ping in 2nd gear matting it at any RPM and just a tad if im lugging it in 3rd and tip in hard in the 1500 rpm range. I feel a bit of relief now that I dont feel like im ruining my engine whenever I drive it.
