Which part # head gaskets are you using now?
Are you driving it now or not?
I was living in Racine Wisconsin and drove it every weekend if it was cool out... I probably have 500 miles on it, but if I shut it off hot the starter could not turn the engine over unless I backed the distributor off about 10 degrees...
I have a dual wide band in it and fooled around with the carb a fair bit to get a reasonable afr for idle and cruise... Unfortunately this engine will ping easier than anything I have ever driven... with a stock mopar distributor I can not get a combination of initial timing & full advance that works.
If I put in low enough initial timing so that it will start, then I have to open the throttle blades so far that it will "run on" forever when I shut it off hot. If I put in enough advance to make it idle with the throttle blades in a normal range, it won't start when it is hot...
I ordered a CB performance black box yesterday, I am hoping that I can put together a timing map that will work with this mess of mismatched parts.
