Cuda, wouldn't a set of 915's work just as good as stealths? The only difference is the weight. It would be nice to have a set of 915 or other closed chamber head on the side in case finances fall through for the stealth heads. I'm still leaning towards stealth because I'm keeping the AC so it will help compensate for that.
915s have 1.74 exhaust valves, but many heads with closed chambers came with 1.60 exhaust valves, not that there is anything wrong with 1.60's on a 383. They COULD be opened up to 1.74 anyways.... The wreckers have been picked over pretty good in the years gone by, finding 915s might be tough, I'm not sure in your neck of the woods...

My 268 Comp in a 400 had a burble at idle, but I wouldn't call it "choppy"... Nice idle, nice power from idle on up, I liked it. It pulled hard.
