Getting "ready" to install 340. Prev 273/904, any reason to be concerned about witness marks? Never seen that before. 1 out of 6 bolts is different depth and head size. 3/4 head is 0.5" thread depth, 5/8 head bolts are approx 0.60" thread depth.
Head thickness 0.26 on 3/4" head, 0.28(ish) on the other 5 5/8" heads.
I have another stash of tc bolts "somewhere" :rolleyes:
Thanks
Steve
