It took you longer to ask the question and read the responses than it would have to just adjust them.

 

Good one!

 

I just don't understand the reason for your question. If you are that qualified, then you already knew the answer before you posted.

 

Obviously, he did not already know the answer or he wouldn't have asked the question in the first place. He was replying to a snarking answer from someone who is a pro at giving snarky answers.

 

I'll be glad when the sun comes back. People can blow that wad out of their paties.
Kroozeabout.

 

Always a good idea to put the push rods back where came from but not something to loose sleep over. Always need to adjust the push rods when ever they are removed for any reason. You will need to read up on specifications as to adjust hot or cold motor. Hydraulic lifters have a self adjusting range but you would like to be in the middle ground. Solid lifters need to be a little more exact, and never make them too tight or you can burn a valve.

 

I really was't paying attention to that stuff. Anyway, I thought it was a strange question the way it was framed and presented in the OP, IMHO.

He has received a few good answers, and his shop manual should lay it out and fill in any details. And, there is always YouTube instruction videos for visual learners. If he has aftermarket push rods, he can google for instructions. I guess it is easy to assume folks have done all of that before asking on an open forum like this. I know I do.

 

I had explained to him the FSM would be his best approach,
and that I am sure he would have already thought of that being he was overly qualified to ask the question...
Then I deleted it as I thought it was too honest an answer and I would get deducted another 10 points, for an honest answer.
SO now you all know the big secret...LOL

 

It's not 100% necessary to re-adjust them. Measure the old and new cylinders. If the new cylinders are different you need to worry about more then pushrod adjustment. You may need to adjust head gasket thickness to keep the proper squish.

If they measure identically you can put the pushrods back in the holes they came from. Just be very careful when putting the rocker support plate back on. Tighten very slowly and evenly. It will crack if not done carefully. Once you get it down let the lifters sit for 15-30 minutes before you spin the motor over.

Personally, I would just collapse the push rods, slap the top end back together and re-adjust. It will save time.

I'm assuming this is a 107" twin cam. If it's an M8, disregard everything I said (except the squish part). I'm not familiar enough with the M8.

BTW - Shop/Service manual will not address adjustable push rods. Also, exhaust pushrods are longer than intake pushrods even for adjustables.
