This had been asked in earlier threads but no "answer" was found on my search.
Have 1956 truck 261 and a 848 head off a 235 engine. I need to drill the holes in the head to match the holes in between the sets of cylinders on the 261.
Is the bit used the same size as he holes in the block?
I also remember a question being ask about "angle", so is there and angle??
I figure everyone uses the gasket as the template?
Any information is appreciated. Deve?? Wayne??
Extra question: I have a dual offenhouser intake and fenton headers. This is a new rebuilt engine, not by me. I pulled the head off to "verify" everything and to get it unstuck. So far all is going well.
I'm thinking about using a single 235 intake to get the engine running and tuned in. It is bored, with new valves/springs ect and has a "racing" cam in it but I do not know the lift or brand.
Until I get healed up from surgery my nephew is helping me.
1. drilling holes in the head?
2. start it up using the single intake?
3. use standard setting for adjusting valves as starting point? (new lifters)
