9.8 vs 10.2 deck makes a difference, couldn't remember what you bought, I guess if you didn't need to modify your existing exhaust you will be ok

Many of the old Cigarettes had 34 inch center to center.

Not sure which generation stainless marine you have , but I can tell you that you will be going backwards replacing stainless marine with stellings headers..in terms of maintenance . You will be testing and fixing those headers every year, been there done that...never again... I will tell you that I had stellings black model and they fit a tighter center than my new stainless marine gen 3 ... Jerry had to make custom center manifolds to make mine fit.

Seems the deal is not as great as I thought, gonna pass I think.

That being said maybe I just make my stainless marines dry and leave them for now

For me, its a no brainer to use GEN III stainless marine on a blower motor. Performance and reliability.

N/A motor, there could be some decent perf gains with a full length header over a gil or sm marine standard setup.

My stellings were made in 1996. I had them repaired once in 2011 for a slight leak. But I dont run in salt either.

Does Stellings still make headers?

Haven't in a long time. I'd bet the newest ones you'd find are 10+ years old

Gotcha that explains google failure lol

For overall (peak) power the full header will be the best bet. But thru the cruise RPM range you won't see a big gain over the Stainless marine. The Stainless Marine sure are more reliable than ay full length header out there other than the Keith Eikert stuff.

I've got the stallings green tag in a 12 meter with 33 1/2" center and have a good 1 1/4 btwn the two center. The only thing to consider is that's with gm heads. Your aftermarket heads with 1/2" raised exhaust ports will narrow the gap a bit.
