F 155 engine in my 40 (Mar. 1970). Rebuilt the carb (Small window SD-40) and decided to replace exhaust/intake manifold/valve cover gasket while I was at it. Cruiser had been sitting for ~25 years prior to my ownership. I've added ~1500 miles since.
Separated manifolds to check for cracks in the intake manifold. Plenty say not to do this to avoid resurfacing. No cracks on either manifold. Re-tapped and re-threaded any and all bolts, nuts and threads, cleaned both manifolds and head/block on driver's side.
Remflex gasket kit (Thickest to prevent leaks). Planning on finger-tightening the manifolds together then mounting them on the block, torquing the nuts to the block (30-35ft/lbs?) and then tightening the manifolds together(Torque spec?). It is recommended to bolt manifolds together and then get resurfaced but both hold up to a straight-edge nicely so I'm not too worried. No plans for a block-off plate because my flapper is intact and moves freely.
Am I on the right track or do I need to bolt them together and get them resurfaced? The ears on the manifolds had half washers on them. Are those OEM? Does anyone have any other insights on the installation? Leave the flapper in or take out? Thanks in advance!
