Lifter stuck?

Some thoughts -
1. You need to verify lifter rotation during assembly and I would definitely measure each lifter bore properly to make sure there' no issues there.
2. You should use the Crane cam paste for the lobes and lifter faces after you verify lifter rotation. The liquids and special oil won't really stay in place - the paste will.
2. The Lunati springs - are they true dual springs with a dampener? Meaning do they have a smaller spring inside a larger spring with a flat wire spring separating them? If so, you should remove the inner springs fort he cam break in period. Then reinstall once it's done.
3. How do you get oil pressure and fuel to the carb? By turning it with the starter? It's a huge risk to turn the engine with the starter to get oil pressure or fuel to the carb. Use a pre-oiling tool and drill, and fill the carb (carefully) through the vents.
4. The cam is only oiled by splash up from the crank when it's turning. You have to have enough rpm to toss the oil up off it - so make sure the rpms can get up to 1800-2500 immediately, and it can run through the whole break in period without shutting down to top off coolant or whatever. Stick a box fan in front of the radiator, and make sure you don't fill the cooling system to the top so it doesn't burp and get all over the place.
5. I also leave the break in oil in the crank case for 100 miles or so, and limit time the engine spends at idle for that period.
