Detailed 216 and 235 "intake" port dimensions are noted in Barry Weeks reply at end of the thread (exhaust ports not discussed). https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=198074 Found using the "Search the Site" link in left forums page margin. It doesn't address the 261 intake size. Perhaps another 'Bolter can provide that detail??? One last note - the carb mounting flange size is also different between 216's, 235's and 261's. Another key tell-tale to help ID'ing manifolds.
