Valve truble

Classic 360 head disaster waiting to happen!

Rotator retainers changed out for stock ones...
The rotator exhaust valve has a unique 'baby spring' form a toy engine...

Last 360 I bought had been modified in this way with a bigger cam and smashed the valve straight through the piston!
???? Now im lost my ex valves is from a earley 70s 360 thay are not rotator valves
