OAI parts: 350 v 455

I see several vendors for OAI stuff show some differing parts for the 350 than for 455 motor. How are they different ? Will look to buy OAI stuff this year on this forum or CL, etc. and I need to know what I buy can be used.

I am pretty sure most of it is the same, the top assembly with the flapper is at least. I'll have to check on the air cleaner base but I thought that was the same - main difference is the foam seal is thicker for the 350 as it is shorter.

I think that's the only difference. The foam needs to be thicker on the 350 due to the shorter deck height.

Correct. The foam is taller. That's the only difference.

the 350 base has a rubber plug in the driver side hole for the crank case breather and the 455 had two breathers, one to each valve cover. the base was the same though.
