Narrowest point at the inch with my calipers is ~1.030 but the height seems to open up (floor and roof) beyond the 2.30" port entry, kind of like "offsetting" so even if the minimum cross section is less than 2.48", I doubt it's very much less at all. As the man said, pictures can't tell you what your eyes and fingers can.

Something Bryce did for rocker clearance is he used lash caps and when I add them now my pushrods needs to be ~.055-.060 shorter. The Comps do clear the springs but it ain't by much and the caps help increase it.

As for the bigger springs, I'm not sure except to think that by going to a shorter/wider spring allows more room to port the roof, (using a noticably shallow spring plunge cut) to give you a comparable seat/open pressure. Seemed like a great app for a beehive


I'm hoping Bryce will home back in, maybe somebody can ping him on YB?
