To be honest, I am having a chitty day, and you always push for issues and pages, and just fuel fires... thats what.

If .010 to .015 of metal came off of the lobes, there would be quite a bit of engine damage.
That is simply not the case.
Pictures on the Internet can be very deceiving.
Again, let's stick to the facts and what has been determined by those who have inspected the cams IN PERSON!

Those engines came from Chicago, and were dyno'd at Fast Times Motorworks back when they were orignally built.
315's have been 'over achievers' on many engines.

Fast Times was and probably is still, good peeps.

Sorry, but I've seen quite a few steel billet roller cams come out of engines, with 5x as many hours, 1 that came out of a factory GM engine that had 200k miles on it, and did not have wear marks like that.

Not buying that story. And realistically, if it was a manufacturing defect, that should have no bearing on Bob Madera's end, so I'm not blaming anyone.

Unless the person who ported them did a before and after on the same bench with the same procedure, or better yet a before and after on the dyno it's not of much use.
Edit- regarding Tim's head porting

I agree, just saying what I was told, I figure if the issue was short duration and high lift, that will be not an issue now, should be anyway..
