Are you wanting just plain plugs or platinum?

doesnt matter just trying to get correct plugs. with old heads i used conventional plugs. this time compression will be approx. 9.5:1 with flat tops. would platinum be worth the cost?

I ran a set of NGK iridium for a while in 1990 model 355 with stock heads with mild porting and 2.02s. I was running 9 to 1 compression and a 600 Holley, a 300hp combo. Ran great, plugs lasted forever til I had to go with Auto Lite shorty plugs to fit under my headers.
