spark plug question

I have a set of 461 dhumps and I've ran 303 autolite plugs in them. I am having issues with plug wire and header tubes coming together. Is there a different plug I can use that is shorter? In our circle track engine we used champion plugs that were mainly for a briggs and stratton but I didn't know how that would transfer to the street. Also can you use the plugs that are made for the beveled plug hole heads?

Accel has short plugs for this old cylinder head. Other than that your choices are very limited.

NGK makes a short plug, so does Autolite, look at their racing plug, #3934 for one.

Spark Plugs

Rowdy, To answer your question, No, you cannot use tapered seat plugs in the old double hump heads, they require a gasketed seat plug. Accel 8197 is a shorty plug for this application. Nolan

spark plug question

The old pre-71 camel hump heads used a R44 AC Spark Plug. If you cross reference a R44 to a NGK it is a B6S or 3510.
