I have been trying to find the intake and exhaust runner size on 14014416 castings. What is have found is they are used in 267,305 or 350's. 1.84" intakes & 1.50" exhaust. It seems to be unclear on the chamber size, as I am seeing 58cc and 64cc.

14014416...80-86...305..........1.84"/1.5" valves, 58cc chambers

140144416
Casting mark on end of head "saddle and vertical bar" Late-model 305, intake port not restricted; lightweight; 58cc chamb comes with perimeter valve cover bolts '78-'84, ('85-'86 center bolt valve cover).

Thanks, but does anyone know the intake and exhaust runner size?

Should be about 155 to 157cc's.

Not -416's, but my 305H0, -601's cc'ed at 160 and 160.+.............

And btw, cc their chambers b/c my -601 heads cc'ed at 53 and 55 vs 58... Only so you will know what they are here is all...... (Stock shaped valves is all here).....
