The Ford Barn - View Single Post - installed a new 6:1 head now a tapping noise

Ok here is the latest on my engine noises and that tapping I have.
I think it is in the timing. One more thing I must add, I had tried the Nu-Rex timing system. Truck run the same with or without the Nu-Rex system. Right now I have it installed again.
I found by retarding the timing it ran better and quieter, so I retarded some more and it is 90% better. Now idles and once again sounds like a Model A. I have read with this head you did not have to advance the timing as far, but I had to severely retard it.
I will play with it some more today and maybe take the Nu-Rex system back out and try it that way so I have control of the advance. I can't believe the difference in the noise level of the engine now, it's quite like it was before. But still think I might hear that tapping lightly as I rev up the RPMs while driving.
Still using the old style points and the bushing are tight no extra play at all so I did not rebuild my distributor, just new rotor, body, cap and points.
