I was able to use the springs that were spec'd for the cam. When I bought the PKG, I called lunati and talked about it with them before I bought it and there was no issues getting in touch. That was about 3 years ago.
During the build, I heard about the sm heads and decided to go with them so I could get away from buying vp leaded race fuel.
Paid for them to be ready to install but the shop didn't get it right.
Couldn't get an answer from anyone and surely wasn't going back to the shop that screwed me.
Wasted hours and hours on the phone, trying to figure it out, hoping lunati could answer it. Never could so yea,
I was pissed off at them, pissed off at the machine shop, and pissed off about being stuck in a no fire situation. Mad at myself for not being able to find an answer so I lashed out because of being stuck without the knowledge to make it all work. So I blame lunati, the shop, and myself.
I wanted to have the motor installed and fired up for the Carlisle Mopar show coming up and the delay was the cause to realize that isn't going to happen now. That was my goal for a while now but I'm over it. I really wouldn't enjoy sitting in traffic with a fresh motor in the middle of July anyway.
I have installed plenty of cams, mainly Mopar or racer brown and always set the spec'd springs and never ran into any problems. This setup was out of my comfort zone and when I got stuck, I felt that it was a big mistake.
All in all, it was a simple answer by shimming but I also was told not it wasn't a good idea to shim that much so I figured it wasn't going to work out but I found the answer and now back on track so I am a happy camper now. Getting hung up on over and over ruined my respect for lunati. Can't blame the heads cuz I don't speak Chinese, and done with the machine shop who was supposed to solve the issue in the 1st place. I am glad that I was able to finally solve the issue and hopefully the cam will work as it was purchased for. Maybe their cams are good, IDK cuz I never ran that brand before and their support line definitely sucks so doubt I will ever buy another but at least I am able to still finish the build now.
