Racing class rules dont allow me to change bigger engine, so I'm stuck with this original 267cid small block. However, I can kick out more power from it, and thats why I'm considering this head swap. I have pair of ported heads with bigger valves (1.94" & 1.6") from a 350cid, will they fit on a 267cid?
I know they have slightly larger chamber, but that wont be a problem for me. I just need to know if they fit and work, or not, before I take those stock heads off.
Nope, you only have a 3.5 inch bore, the 350 chambers and vaves will be outside the bore diameter. The 305's quarter inch larger bore is a just at sometimes with a 350 head.
