Well, this weekend will be the day I finally order the rest of my winter mods - I'm purchasing the rest of the GPI SS1 cam kit (I bought the cam on sale for black Friday and waited on the rest of the kit

)
Build weekend is looking like the back half of March. Taking my pretty much stock 2015 1SS with a rotofab CAI and catback and adding:
Stainless Power LT headers and HFC
VMAX ported TB
GPI rodmod intake - ported and polished
some BMR suspension stuff
new tires finally (thank God)
and the GPI SS1 VVT cam kit
I need to purchase the full cam kit less the cam, and will also be purchasing the EFI Live remote tuning to be done by Ryan at GPI. I would love some input or review of the last things to purchase before this baby is ready to be worked on.
Main questions - what are you thoughts on upgrading to ARP bolts vs the cheaper GM bolts they sell. 8 lifters to remove AFM or go for the full 16 (car has 26,000 miles on it). Do I need to worry about upgrading to a melling oil pump or am I likely going to be just fine? Pushrod length, they recommended 7.400" for my application - is that correct or is it possible you all recommend the 7.425"?

Thanks ahead of time for the input - super excited to be ordering this weekend!
