One of the first upgrades I did back in '97 was to add Clifford headers to my '65. Here is what I found: 1) I did have to bend the throttle rod to get the full movement on the carb throttle. I also put a slight "dimple" in one of the header tubes too for clearance. It's not a big deal real...

Re: Did a '63.5 170 come w/hydraulic lifters?

The combustion space can be reduced "quicker" by decking the block before the head. The bore in the block has a larger area than the combustion chamber, so with each 0.010" pass with the milling machine the CR will be increased more with material removal from the block. Obviously some...
