I am in the process of building a extra engine for my car. I used a hyd roller in this motor so the lifters are taller, different pushrods needed. There are a lot of posts about the dove rockers breaking from pushrod interference in the cup area. I talked to dove and they said to make sure there is no interference in the cup, yours should be ok with the clearence you mentioned.

Since the pushrod length doesn't affect the geometry with shaft mounted rockers and you only have the 2 or so extra threads showing it shouldn't be an issue if you can properly adjust the rockers with the pushrods you have and still have a full engagement on the locknut.

If you insist on buying new pushrods just find an old fe rod, cut a section out and thread it to accept a 1/4 stud and make an adj pushrod to send to Smith Brothers at the length needed.

Just my 2 cents worth.
