cb750 K1 cylinder head

[750rideruk]

Preparing to renovate the top end on my K1. The new gasket set includes 8 valve stem oil seals but only the inlet guides had them on in the strip down. Also only the inlet guides have the groove to locate them. Do I fit all 8 seals, my thoughts are that the exhaust seals will not stay in place.
Help please

Only later heads had 8 stem seals, if no groove don't fit them or change the guides for later style ones
