? Valvetrain Geometry ?

Is there any possibility they cracked because they were so loose on the shafts that you had to have them bushed please dont take it like I'm blaming you I dont mean that at all if you buy new quality parts they should be good out of the box and you should never have had the clearence issues in the first place I was just wondering. I don't know I was just wondering I'd like to order them for mine but with the horror stories you have I guess I will have to think this over a little more. Thanks for sharing Justin

I don't think so. They were not cracked in the same place on each one. I believe it was poor metallurgy. Also, on the adjusting screws, some were tight in the threads, others were WAY loose before they were run. It's a QA problem.

It's my personal opinion that MP "quality" is nothing more than marketing.

My apologies to the OP for hijacking this thread.
