spark plugs for a 383

What do ya all reccomend for this flavor: engine:::: 383, 9.5 compression with open chamber heads, MSD ignition, crane roller cam with 1.6 intake rockers and 2.02 valves. AirGap Edelbrock with a Carter AFB ( now Edelbrock) 750 cfm. Hedman 1 5/8 long tube headers, Flowmaster (or equivalent).
I was thinking, go to the parts counter and get a plug that a 350 with HEI used and good enough.

Now if you favor a different version or brand or what have ya please let me know.

Re: spark plugs for a 383

I ran Autolite 26's in my 383. It is a hot plug,you can go lower in the heat range. Go to a GOOD parts store that actually has parts BOOKS and ask for a plug book. Go to the heat range section and go from there.
