I got a set of stock e7's that im ripping apart for some porting experiance. When I compress the exhaust valve spring i give the valve a little tap and the retainer slides down and the keepers pop out and the vavle comes out. Not so lucky on the intake vavle springs. I compress the spring and the retainer doesnt move and doesnt let the keepers come out. Whats the deal here?

Tap lightly when compressed, they are stubborn
