Bone stock internals, just have 1 7/8" Hookers, Weiand intake and Eddy 1406. These plugs seem to be fouling slowly. Slight tan on the strap area, the ceramic is turning black with crud and I occasionally get a shitty idle for a few seconds then back to normally. Not sucking oil into the intake as I just put a new intake and gaskets on ( that was a previous issue, old intake was milled). That's all good now. Sometimes helps revving it and then idle smooths back out. Carb dialed in good, ignition is stock and shows good with a DVM. Idles good when not stumbling, pulls great for what it is in a 71 B body with 3.23's. Would it help to go hotter to the XR4's (5858)? Other than this, the thing runs awesome. Appreciate any help
