Hi! Assuming I get my distributor to drop in my freshly rebuilt '57 GHawk 289 (yes, just read some posts with suggestions....) I'm going to finally set the valves... Reading the shop manual, "cold" is .025-.027", where "cold" is defined at "70 degrees". SO, since in Minnesota is 30F this afternoon and DROPPING fast, and my shop is only heated when I'm out there (ie: block is going to be ambient temp...), should I add a thousandth or two and shoot for like .028 max ? The "hot" spec is only a couple thousands LESS than the "cold" setting, and a lot more temperature differential (assuming a 'hot' engine is thermostat temp of 170F or so).
Guessing stick with the .025-.027" but thought I'd ask; never noticed the reference to 'cold' being an actual temp (70F) before.
Thanks!
