Installing bigger roller cam..Iron head 427 When i got this motor it had bad intake guides....really really bad.
Exhaust are fine...both heads are worn the same....I eyeballed the mid lift angle when i first got it and it looked plenty close and this is what i have right now with new cam.
The roller runs on the outside edge of the tip....It is what it is....
The intakes run a little closer to center.
Mid lift angle looks fine to me.
Trying to avoid any more guide issues....
Anybody want to hazard a guess what would cause guides to wear that much and do it pretty evenly...and not have an issue with the exhaust guides at all. The intake valves themselves are still good..stems were smooth and not worn....
Harlan Sharp rockers pushrods are 9.350/8.380, no excess wear from guidplates.
