I have some. What length do you need? ...& Summit also sells them individually. So, not $80 bucks if you're just changing a few.
Hmmmm...wonder if the previous owner correctly measured the pushrod lengths. It does have an aftermarket cam (not stock) correct? If there are bent pushrods there may also be collapsed lifters. Did you run it & watch to make sure that the lifters are pushing oil up through the pushrod & into the rocker? Local from Summit is overnight. So, a phone order placed by 6 PM, or so, usually arrives the following day.
Nasty (Corey), I'll be sending a Text.
