Autolite AR 52 or AR-53. Try, and, read plugs ,should be close.

If you like drag racing, support your local track.

That 65 is probally a little hot for the compression ratio, try a 64 or 54 Or as already recommended the 3922 also That is a 5/8 body plug so don't be suprised if you buy a set. I like the Champion RN9YC or RC9YC (5/8 body)for those heads with that compression also
