Cam bearings installed wrong, ( covering the oil gallery holes up)
The push rods are stoped up.
DID YOU PRIME THE ENGINE OIL SYSTEM ???
I think you did not let it run long enough for the lifters to filll up with oil.
There is also 3 oil gallery plugs in the front of the engine behind the timing cover
right behind the cam gear. If they weren't put back in then the lifters won't fill up with oil. It will just push the oil out the front of engine. ( NO OIL PRESSURE ON TOP )
A spun cam bearing, or just bad cam bearings period. Push rods stoped up, Need cleaned.
To convert your 1971 Olds 350 Rocket to a full roller rocker setup, you'll need to replace the stock rocker arms with full roller rockers designed for your engine. Start by removing the valve covers and rocker arms, then install the new roller rockers, ensuring proper alignment and clearance with the pushrods and valves. It's also advisable to use compatible pushrods and check the geometry to ensure optimal performance. Finally, reassemble everything, double-checking torque specifications, and adjust the valve lash as necessary.
The rocker arms are probably adjusted too tight and hanging valves. Or the rings were installed incorrectly. You will be lucky not to need a new cam if it's you rocker arms.
Take off the valve covers on the top end of your engine. Remove the rocker arms and the push rods will free up. Pull each push rod out one by one inspecting each to see if any of them are bent. For re-installation prep the heads by cleaning any residue on the housing. Inspect rocker arms as the new push rods have to re-seat unless you purchase new rocker arms. Replace gaskets and seal with RTV after the arms and rods have been properly torqued. Good Luck!
there is one way to do this short of installing a new cam shaft. small block chevys came with two types of rocker arms. one is a 1.5 ratio and the other is a 1.6 ratio. if you have the 1.5s now you will get more lift changing to a 1.6.
Your best bet is to buy the manual. There are multiple ways of adjusting rockers and it depends on the vehicle. Your loose rocker arm may also be an indication of a bent push rod, bent valve, or worn out cam. there are 2 types of rocker arm studs pressed in and threaded in. if it is pressed i suggest buying the same size threaded stud, tapping the hole and using 2 stacked nuts screw it into the hole in the head. if its threaded just remove the old one and thread in the new one, be sure to check torque value for this application answer if a rocker arm is broken, u need to remove rocker cover the rocker arms are all on one tube bolted to the head remove the nuts that secure this tube slide as many rocker arms as need to get to broken rocker arm, off the tube replace with new rocker arm replace others that u needed to remove. sit tube with rocker arms back in place making sure that u align all rocker arms to the proper place tighten securing nuts to proper torque over tightening will break the studs then adjust rockers to specs if engine has hydraulic lifters you will not have to adjust replace rocker covers using new gaskets if the rocker ram is loose, adjust to specs if engine has hydraulic ligters, torque to specs job is done
* the sun cam from the galaxy and the space all planets revolve around it
1. remove valve covers 2. remove rocker arm nuts and place rocker arms in order as u take them out 3. pull the push rods out 4. loosen all head bolts and replace them with new ones for more accurate torque when tighting 5. clean the block where the head gasket goes and the bottom of head 6. spray head gasket with copper coating and lay flat on the block 7. place new head directly flat on th block 8. torque head bolts from the center out to insure proper sealing 9. insert push rods and rocker arms and nuts 10. adjust valves for proper motor function
Worn or bent push rods or worn rocker arms. Incorrect adjustment procedure. depending on what type of lifters some of them have to be pumped up manually .Worn or bent push rods or worn rocker arms.

If you want to put just the yfz450 shocks on a raptor 350 and not buy new A-Arms because you can buy extenders. Because i just bought their +6" A-Arm extension kit on eBay They have a kit specifically made to fit the 450 shocks on the raptor 350. It is under 100$ and its way cheaper than wider A-Arms. http:/stores.ebay.com/Diamond-J-Customs
Stick with Classic 350 on regular gas. I'd go with an 87-up 350. The one-piece oil pan seal and raised-rail rocker covers are less prone to leaks. no by fare use a new motal better evry thang
Check the pressure regulator, fuel filter and fuel pump.
