if the heads are on block and you dont plan on taking them off . shoot some air in the cylinder, i like to use a leakdown gauge and pop the old off and replace with the new."IT'S 106 MILES TO CHICAGO , WE GOT A FULL TANK OF GAS , HALF A PACK OF CIGARETTES, ITS DARK, AND WERE WEARING SUNGLASSES"
"HIT IT"

If you don't trust the "air" method or don't have a compressor, you can use nylon rope. Pull the plugs, put the end of the rope in the plug hole and then turn the motor so that the rope wedges against the bottom of the valves. Change the springs, turn the piston down and pull the rope out. Don't use the yellow rope, it sheds to many fibres. Use the white flexible rope.

thanks i like the rope idea
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
