Scary when you do drop a valve while doing the above procedure
I have done it on an old Lincoln with a 7.5
Got lucky and was able to rotate the piston back up slowly and up popped my valve back thru the guide
A real sweat fest
You will hear pro and con on triple springs but that is what I run a Crane Blazer cam and the corresponding Crane triple springs they recommended

I have them on a Boss 302 motor I built
Cleveland heads
Not real sure of the specs on my springs (I built that motor in 1982 or so)
Roughly 325 lbs on seat and 900 lbs at 1.6 height

1.600 sounds really short for a Cleveland head is that why your loads are so high? I have a customer who uses triples on a 618 with IDT heads. I think that they stack at 2.200 and when I test them I have to beak them apart and test each spring separately otherwise I can't get them to coil bind without overloading my tester's load cell.

These are not my springs and the seat pressure specs are partially cut off. They are available in several configurations for each set of heads. My heads had to have the spring seat cut to fit the bigger spring base I think

900 lbs is the manufacturers spec for spring load at a certain height
The 1.6 for the spring I referenced was not my spring
I bought the cam and kit with their springs (pimping their stock they said their triple spring setup was required for my cam)
