The heads on both of my mid-70s C&Cs were installed with ¼ or 5/16ths stainless hanger bolts. A hanger bolt is sort of like a threaded rod that is threaded like a machine screw (bolt) on one end and like a lag screw on the other. The material under the platform on which the head sits is ¾ plywood, and there is no access to the bottom side without major surgery and a lot of hassle.
When I replaced the head on the 25, the pattern of the existing 4 studs (hanger bolts) did not match the pattern needed by the flange of the new head. I removed 3 of the 4 existing studs with a pair of vice grips, marked the location of the new holes and drilled 3 pilot holes, and reinstalled the same studs (hanger bolts) in the new pattern. Took maybe 30 minutes to move the studs and squirt some Boat Life into the old holes to seal them. If you damage one of the hanger bolts, or if you just want to use new ones, they cost about $.50 each at Fastenall, or your local Lowes may have them (although I dont know that all Lowes stores stock as much stainless as my local store does.)

What suggestions do listers have for bolting this in place. There does not seem to be any access under the platform the current head is on. Toggle bolts have been suggested. Or creating an inspection port for placement of nuts/washers. Is there anything under there I need to worry about damaging? Thanks. Bev Genader Bob Morgan C&C 37
