Vortec Head Valve Seals Help/Recomendation

Just picked up a set of heads on the cheap, $50 for the set.

Need to replace the valve seals, but the local auto parts stores dont have what i seem to need.

My valve guide boss is measuring .550-.560 (battery is dead)

The felpro listed for Vortec Equiped heads were way to big, inner diameter of .580, seems like they would have popped right off.

Any recommendations?

Thanks

Just a FYI Vortec Heads are very prone to crack , I would have them checked to see if they are any good before started spending money ...

There were two valve stem sizes offered. HD truck engines had larger stems.

NDT testing, a machine shop can do it. $50 for the set tells me they are cracked, hopefully not.
