well after removing my valve covers it appears that i have solid lifters or someone put poly locks on on the rockers-it also looks like i have different heads on this #3917291-d77 is stamped.
with out any info on what settings this needs what do you recommend?
if their solid lifters you be adjusting them a lot, they require allot of attention.
That doesn't match my experience with solid lifter small blocks which goes back more than 50+ years.
The last time I adjusted the solids on my FI '60 was 2013 and that was only because I had to R&R one cylinder head. Before that..... well, I don't remember but it was probably around 1984.
Bottom line, solid lifter engines are not high maintenance.

Installed them on my '67 L79 when I did a cam swap and valve job. After 500 mile run in, I switched to roller rockers and back to standard rocker arm nuts.
I have solid lifters in my '61.. No locks on them.
I set the lash before my 6000 mile cross-country trip last year, plus a 1200 mile trip this summer.
Checking them after I got home, after 10000 miles, 2 or 3 had drifted slightly.. maybe .002. max.

Myth
291 heads were GM parts replacements for just about any of the early 2.02/1.60 units.
You should pull the Manifold and see what you have, 695 top oiling type solid lifters or 585 top limited oiling type solid lifers. As you have roller tip type rockers, I would run the 695 or comparable type lifters as they aren't full rollers. The adjustments are more determined by the camshaft, so you will need to ID that.

Measure the current lash adjustments both intake and exhaust, Then maintain that lash setting….. (if you find a few that are looser than most, just adjust them to the “majority”). Who knows what’s in the engine? Could be a 097 cam, could be a 30-30, could be some aftermarket thing.
Think the "adjusting them all the time" came from one of two things
-Not being adjusted properly in the first place
-Using the factory nuts over and over..you can ( Ihave) but they are supposedly 1 time use pieces
they can get loose over time. Probably why the guy put those polylocks on there bet that lash never budges.
Like adjusting solids with the engine stone cold, 1 cyl at a time. EOIC method..takes longer but its foolproof.
Love the way they run....kinda seamless like that OHC feel...and of course the sound.
