Push rod selection?

Hi guys,
I'm ready to order new push rods for my 496 build. I'm looking at Chromemoly but I need 7.550x7/16 for my intake valves and cant find them. The exhaust I need 8.450 and 8.500x7/16 and can get them from Summit but don't see any as short as 7.500 for my intake. Anyone got any ideas? I'm not sure if I can get them custom made and if so how expensive they will be and how long it will take. Id appreciate any feedback on this its my last order for this engine and I should be able to test run it. Id like to get the body back on before Christmas.
Thanks

Custom ordered pushrods. Crane has a form on their website. They will give you a quote on the price.

Thanks for the replies. Someone else suggested Manton also so
I asked them for a quote
