Actually....those are not the correct lengths for my stock 350....I just went through this...I initially used the 2.5" & 3" lengths, but I wound up bottoming out in several of the holes before they tightened....

I then ordered a correct kit from one of our site vendors and they came in 8 ea. @ 2.25" & 4 ea. @ 2.75" (centers).....they were perfect!

It's my understanding that you do not ever want to bottom out like that as you can cause major damage...
