Old sparkplug / new sparkplug
Old is proper plug to use cause it is a chamfered seal type plug. The new sparkplug is a bottom type sealng plug
Take your eyes, look from the bottom of each plug up the threads and notice as the threads end, old plug has a chamfer and the new plug is a square shoulder. All modular heads are chamfer sealed. Something like a lawn mower engine is bottomed / square shoulder sealed. I cant remember what pushrod 302's but they may be bottom sealed as well.
