So around 9 to 1 compression, I would run a hot plug. You probably need less timing with the more efficient chamber, I like a lot part throttle with factory Olds heads. These would probably work. https://m.summitracing.com/parts/ngk...ns?prefilter=1

Thanks to all for your reply's ....
My reason for not using Champion plugs goes back to mid thru late 70's I was a flat rate mechanic @ an Olds dealer . The parts dept. went to Champ. plugs to save $ , I did more then 1 tune-up where the car ( Oldsmobile ) came in running fine ran like crap after replacing the plugs with Champs ( only under a load would break down ) I would replace them with AC plugs car ran fine - would loose my A$$ on a simple tune-up which would normally be a money maker , but yet they were fine in Chysler products and small engines don't know why ?

Then you had the wrong plugs in it. The plugs aren’t human and have no idea what “brand” engine they’re in. That’s the stupidest thing I’ve ever heard. You had the wrong plugs in it, or they were simply defective, plain and simple.
