I had a hv/hp oil pump in it up to about 4 months ago, I took it out and put in a stock pump. That put a stop to chewed up distributor gears, and my pressure went from 75-80 warm to 60-65psi. That didnt fix the fouling plugs problem. Im using ACdelco plugs, FR3LS I think. I know my jetting, powervalve,timing, and plug heat is right on the money so its something else. My engine has no more than 10000 miles, but I had the heads apart once and reused the seals so its possible they are leaking.
All I know is that my valves look like crap, looks like someone stuck a big piece of black bubble gum on each valve. I think Im gonna pull the heads and start from scratch on the top end, and get new headers.
