Re: spark plugs

hey, i saw this thread and did some research and found a site that has AC 43 can i use these plugs as i like the style and the AC 44 are out of stock and im not sure about hotter or colder plugs i have a 66' 283 stock cam and pistons no valve work bare bones stock, my question is will it be wrong to use 43 plugs to get the same effect or should i hunt down some 44 plugs? thks
