[FC] push rod oil tubes

[RON BLOOM]

Good afternoon

I have a question concerning replacement of the o 'rings on the push rod tubes. My thinking is take the bottom row bolts outs all at one time, replace O rings, reinstall, then tighten in sequence the head bolts. On the top row maybe add a couple of pounds of more torque. will this work? Anyone have better suggestions? This on a 110  eng, I would assume this would apply to all engs if one wanted to replace the o rings...

Thanks in advance!!
