Valve stem seal questions

I have 95 f250 with 351w that I rebuilt the e7 heads on and I think I put in the positive lock valve stem seals in. I was told that this is my problem as the heads use umbrella style seals. Instead of pulling the heads again, I have a rebuilt 357 (nonroller) with crane 44232 cam, gt40 heads with 1.7 RR and all new gaskets in. I am going to put this engine in and rebuild this roller. What style seals do the gt40s take so I do not install this engine with the wrong valve seals installed?

Also, I need to replace my valve covers and wondering if the valve covers I bought will fit.

I used my stockvalve covers prior with these rockers and didn't notice any issues, but that doesn't mean that there weren't...
