Re: 5.5 head
I do what Bob does by timing my engine with the spark advance 3 or 4 notches down. I have a 6.5 head. I still change my timing to match conditions but at a lower position of the spark lever. With the higher compression ratio the spark advance does not have to change with RPM as the burn rate increases with increased engine speed. I will retard the ignition one notch when lugging or driving in town and advance one notch when cruising on a level road with reduced throttle. I start the engine with the lever 3 or 4 notches down. I love to listen to a low idle and can get a really low idle with the lever all the way up and the throttle cracked.
