i think the number you mean is 398268.....398268 and 398269 were the part numbers...331490 is the casting number for both....they were machined to two different chamber depths..
200 had smaller chambers than 225...i have one used 200 head and one new 225 head...the 225 head can be shaved to match the 200 chamber depth..Last edited by BOATMANBLUES; 07-17-2019 at 08:24 PM.

Okay I’m picking up what you’re puttin down. Yes a litte
mixup on my PN there- I was testing you, you passed. I’m looking for the heads that have the larger chamber depth, I believe it’s .700 and the other is .675. The only knowledge I have of this is from poking around through old reads on this forum. But from what I’ve learned I want to go with the deeper chambers. I thought that part was 398268. So you’re saying you have 1 of what I need?
