Cam Components Questions
Summit sends a return label and instructions with every order. There is a customer service # on it. I have found them very good for returns
So, all is well now, the correct ones are dual springs and the retainer actually fits.
You might want to try the Proform tool I noted earlier
Glad Crane got the right retainer for their kit. Someone in packaging FU.

If there is a gap between tool and valve tip you measure that gap with a feeler gauge and subtract that from your stock PR.
or you could use the adjustable PR and adjust till both sides sit flush and then measure the adjustable PR with a caliper to get a PR length.
Lets say you wind up with a length of 7.185...just use your stock 7.200. If you wind up with 7.135, get 7.150
Off the shelf PR generally come in .050 increments so just pick the size closest to those increments.
I use the Crane 99473-1 tool which allows doing both intake & exhaust valves same time per cyl. Not cheap but years ago when I bought it was $100 then. "Tims Tool" is a knock off of the same thing. It was for 3/8" studs but I drilled it out for 7/16"
You should not have "bent" the RR studs using the Proform leverage tool...so confirm you are using it right. 3/8" studs are more prone to flex than 7/16" ones but still they should not bend
6.9xx" was what you got???
your head & block have been decked/milled?
if that is your measurement get 7.000" PR. I wound up with 7.100. Every motor is diffrent so that is why you measure
Yeah I was quite surprised too, seems like from what I read most people still ended up with around 7.2, but I checked it and re-checked it many times on many different cylinders before ordering. I believe that my heads and maybe block were decked back in 2008 when I rebuilt the motor. It overheated and blew both head gaskets on the highway, I tried to limp home and it got worse and seized up. I sent it to a machine shop back then to do the work, and I believe they did it then. That would definitely explain it!
My question is, should I fill both heads with oil as well as the lifter valley before I put the intake and valve covers on? It seems to me like it would make sense to evenly distribute the oil to help it cover everything on startup. I did use the Comp Cams Valve Train Assembly Spray 106 to coat everything, but thought the oil would still help. What are your thoughts?
Your head & block being decked is why you wound up with the shorter than stock, 7.200", PR. Good you measured for them
