Of course. This doesn't end here. They'll measure everything out once the short block & heads comes back from the machine shop.
I refuse to be the only one who gets bent over in this situation when I did nothing wrong.

This cam is friggen HUGE, it would be my opinion only a full lockout and a fully blueprinted install would suffice, clay it, check the install height of each spring, verify coil bind. spin the engine and see if it is reasonable of a non-roller tip rocker over the contact area of the valve stem. Heck many of you would remember that I was all for the GM perf cam with sub .600 lift just because I trust GM AND I don't like .600 plus lift cams on DD. That is me, Pray talked me into this baby blower cam and I'm 100 percent happy, especially because of the fuel lobe.... idle is bad action too just saying... but this stage III cam... my god, there is a lot of lift and duration especially on exhaust. Only a fully locked and blueprinted setup, meaning TIME would be acceptable.

My shop basically said the same thing, in fewer words.
I trust GM manufacturing far more than any 3rd party. It's a shame they don't offer more aggressive performance products.
