Make sure you get the correct "reach" plug for your heads. I have the 049 oval ports and run ac delco R43t, which are the short reach.

Long reach=.750
Short reach=.460

Been running Autolite 26 in my 049 heads for years.  Gap varies (.035-.040) depending on what ignition I'm running.

The problem with America is stupidity. I'm not saying there should be a capital punishment for stupidity, but why don't we just take the safety labels off of everything and let the problem solve itself?
