I'm a big fan of using what you have. Depending on the condition of your 153s you could almost build both with one v8 kit. Pistons, rings, lifters, rod beatings, valve springs, valves (maybe some head work). V8 kits are pretty cheap. You would beed Gaskets & main bearings.

For the 181 if needed you could most likely re-jet your carb. I doubt milage would change much. The bigger engine wouldn't be working as hard. You would gain some bottom end torque, handy in a 4x4. I have a complete 151 (iron duke) from a '80 ( I think) YJ ? It has a 2bbl carb and that carb and intake might fit some of the 181 heads. I believe it is progressive. I need to find something to stick that engine in.

I hate having to make these choices. It is one of the reasons I have so much junk sitting around.

I thought about that. I happen to have two 153's, (both of which now need a rebuild), and I'm not sure I really need the extra HP from the 181, and resulting decrease in gas milage. I'd need to move up to a bigger carb, (which wouldn't be progressive), and fuel economy is a real concern for me as the CJ2a tank is only 10 gallons, and my driving is typically into the woods, away from any gas stations.

Aha, two messages that I felt were spam from 2022, I thought I'd opened them, but maybe not. Both were "I have a friend who has the parts your looking for".
