Thank You Gassers Rule, I use Autolite Racing AR3911's because that's what the guy who built the motor put in. They come with Washers & when he put the original plugs in he used Washers. I will call AFR tomorrow & ask 'em about not using them.... Fun? ha, ha, ha... But seriously, it's really no big deal to change the plugs in my '32. I remember about a year ago when I changed the plugs {& wires} in the '94 Firebird that I had. NOW were talking about NO FUN, for sure!!! .... It took me 3 days, although not 8 hour days, still it was a REAL pain it the ***. AND when I finished I had no A/C!!! Yeah, I knew my '32 was almost done so when problems arose I just grabbed the hack saw!!! {& no oil pressure gauge} Thanks again Bill
