Question about the 1954 Chev 235 Valve adjustment procedure.
The 1954 shop manual says heat up the engine, lubricate valve stems, adjust valves.

Other information I have found indicates heat up engine, Place #1 cylinder to TDC, then from front to back adjust valves 1, 2, 3, 5, 7 and 9. Use your feeler gauges to set the clearance of 1, 5 and 9 to .018”. Set the clearance on 2, 3 and 7 to .006”.
Rotate until BB lines up with pointer again, then set 4, 8 and 12 to .018”. Set 6, 10 and 11 to .006”.

Which is the correct method?
I'm assuming my 235 has solid lifters (stock engine)

Engine #0805600 F54X
Block cast # 3701481 , 3702436,3835911
Head # 3835913
