quick question and i dont want to sound stupid lol..... i got a 90 iroc 5.0 305 tpi motor.... is there a difference if i use plugs for the same year but for the 350.... i got bosch platinum 4's and denso iridium (12 bucks each) plugs for the 1990 350 tpi can i use the iridums in my 305? yes? no? i always thought sbc is a sbc and you can use any sbc plug but someone please let me know thanks Jared
