Thank you sir for the response.

You would be throwing in the towel after the work you have done. What do you think the dealer is going to do that you can't do? You don't have any idea what the dealer techs will do; all beyond your control. As I said in my previous, your situation is not uncommon for a first time cam install. I still get nervous every time on the initial start up of a new build or cam install. I am not a professional but have done a few; the rattling is nerve wracking but just part of a process. I don't even prime lifters anymore, I just let them rattle until they stop. Lots of help here from guys that have been where you are with a problem so stick with it and keep coming back for help. Solve the problem, crack open a beer and pat yourself on the back for job well done.

I agree with the “give it another go” crowd. You did all the work so far. Just back it up and redo the pushrods.
I personally wouldn’t pay a dealer for what I can do myself.

I just hope my mistake didn't do any serious damage.

If you even made one. Don’t over sweat it. Sounds like you did lots of research before starting.

I will admit, they didisassembly, cam swap, and reassembly up to pushrod adjustment was fairly easy due to reading the manual and watching videos. The pushrods and TDC had me a little off. Not to scare anyone, but I used to work on helicopters in the Army lol 😆. I'll wait for the jabs and jokes to start.

A map isn’t going to make much difference at idle. It’s really for overall performance and/or effectiveness.

Were you responsible for torquing the "Jesus nut".

The two most common mistakes made in a first time cam install are incorrect pushrod adjustment and cam timing. Even if both those mistakes are made, the motor will start and run without damage. It is possible to ding a piston with a valve while adjusting pushrods if the motor is rotated before the lifter has bled down.

Glad to hear you are going for a do over; you will be glad you stuck with it when you are on the other side of this little problem.

Lol, I have torqued the jesus nut before. Did depot level maintenance. Fun times but I enjoyed flying them more 🤣.

Dannnnnng so dinging a piston with a valve. Stupid question, but if that did happen with my current issue, should I do something to inspect for damage or readjust pushrods correctly this time and run it?

Can't thank everyone enough on this forum for the help and being so position and supportive with their answers.
