Home. It was in winter storage in NY. Thought I'd be able to drive it on the trailer and enjoy it when I got home but the gods have other plans all the time

Should sound awesome pulling in the garage under the townhouses. 🤣
 
There's a lot of pooled liquid oil/fuel on top of the intake valves. Hoping it's from me getting the carburetor off. There's definitely oil though. Not entirely sure where it's coming from, if it's being sucked up from lifter Valley


 
All the lifters appear pretty scraped up, with some grooves catching my fingernail

 
^^^ to me, that looks like the cam lobe thrust the lifter against the lifter bore. If it was a tight fit, I would expect the scratches further up the lifter. It could also explain the metal debris. Lifter digging in and scrapping shavings into oil.
Can't tell if it's the lighting, but does that push rod have a burnish spot about half way down, like it was rubbing?
 
The pushrods only have marks where the guide plates are. The awful design of these guide plates don't allow you to get perfectly centered.

Some of the rollers do have a "line" on them. I've attempted all day to post a video of it and my phone won't load it to rumble or YouTube so we're shit out of luck at the moment
 
I ordered Johnson reduced travel 2222sbr lifters with axle oiling. Made in USA. Cost out the ass. Just keep adding this shit up

What does a picture of your underwear have to do with this thread🤷‍♂️
 
Heavy duty aluminum foil is about a thou thick, I think.
You could try sticking a strip in the bore and seeing if the lifter will easily fit in.

I just miced some Reynolds.
Mine is .0011 ± .0001.
 
I didn't see the debris on your magnet. Does it look like damaged metal, shiny or more like casting flash and machining grit ? You mentioned the block was very dirty. What's the odds the gallerys had lots of shit in them and it pumped it up top, causing the scratches on the lifters etc. and leaving the flash/crap up top. I think you used a jomar, hopefully that saved the bottom end.
My buddy has the same block I believe and his lifter bores were on the large side of spec, or a bit over spec. I doubt you have too little clearance, especially if lifters are .873, but who knows. And a bit extra shouldn't cause an oil "leak" to the point of not oiling up top.
Have you checked the oiling without a rocker, as in is the pushrod tip correct for the rocker ?
Is there a plug missing in the block anywhere causing a leak.
Also, a sticky wrist pin can sound like a lifter
 
I'm looking for a good photo of the valve springs. Could the inner and outer springs and dampers be rubbing together and shedding magnetic debris? Are the retainers undamaged?

I have since thrown out all traces the metal so can't really say what it looks like. Mix of casting flash and small specs maybe.

The lifters were "gritty" going in. I brought this to the attention of the shortblock builder who told me to put sandpaper on my finger and just run it through a few times. I almost blew a gasket and said you want me to create metal shavings in an assembled block (I had everything else installed at that point). Anyways, I didn't bother and it may have bit me in the ass.

My lifters measure .8715. I don't know what the bores are. I think dart lifter bores are machined to .8730 so you can open them up if you need to. My new Johnson lifters he said you want .018-.020 lifter bore clearance. I have to verify this when they arrive. I did not check oiling without rocker i installed, but they would seem to be correct.

I don't believe any plugs are missing. I don't believe the sound was in the bottom end. I had a friend verify the noise who has been an arbitrator for adesa for 20 years. He listens to engines knock and tick day in and day out and I trust his opinion since he was there in person with me. His opinion was top end valvetrain.

Since I'm the one that stuck the heads together, it's possible the springs are rubbing together but how do you prevent that? They're a tight fit. Retainers and locks look fine to me.
