Osco CVCR818 manifolds

[erock194]

I want to replace the manifolds on my 260 Merc. the ones that are on it are Osco CVCR818's. Can i replace with a different model Osco or Sierra 1953 model? They are less expensive and more widely available. i have 3" Osco CRR-1 risers w/10 deg. angle.
Thanks in advance for any info

Ayuh,... Donno what those are,...
The 260 is the standard SBC bolt pattern,+ ya gotta get to whatever the downstream connection is...
I would guess just How ya get there, don't really matter...
