what spark plugs are best?

Hello
this is a 72 elcamino 350 sbc stock engine with a mallory unilite dist. and a accell coil and wires, the point dist was removed so i figure to use the plugs for a 72 point dist would not be right.
what plugs should i use? ive heard alot and used alot but want to know which is best theres so many different numbers or series of plugs possible im not sure which to use. ive used r44 r44t r44ts. i know some plugs burn hotter and colder than others so help!

Run whatever is cheapest and speced for stock application for that car. The conversion from points does not affect the type of plug you go with. Gap to stock specs as well.

re rick
you're saying whatever will work. i know that but when you look up the plugs for a 72 its a different style than an electronic distributer like an 82. so i guess im asking now is which plugs are better for an electronic dist. setup? i know that different plugs burn hotter than other others but im not sure which is which. if i ask someone at any auto part store what to use they give me 5 different options and they no nothing about spark plugs and try to sell you the cheapys. i want to know whats the difference in plugs numbers maybe theres a site that can help me out somewhere i don't know about, im just curious about the styles of plugs to see if one will last longer than another or not foul out as quickly.

If it helps you make a decision I use Autolite AR133 plugs in my hotrod.
AC Delco R44TS for everything else.

PS,
With those two manufacturers, higher numbers means a hotter plug.

I used AC R45TS in my 350 for some time. They AC are my favorite pulg. I'm not too fond of Denso, but Accell plugs are made by Denso and are available in a shorty style, so I use those to clear my headers.
