273 spark plug mishap

Thanks to both of you, yet I feel like just replacing the motor since I have another 273 and a modified 318. Just a hard choice at this time with the weather being as beautiful as it's been and having 3 running vehicles. I always wanted a 65, so I may sell or trade this and drive my 64 for the summer... Who knows what I'll do as I am beginning to feel my age and my strength is being knocked out of me.
