hey guys,

when i did the build up of my motor i had the machine shop install some sparkplug inserts (don't know which) and now the heads use a gasket style plug. ( the plug looks like it has a o-ring on it) i am currently using ngk # 5671-7 on the truck. but i wanted to go w/ denso it-24's but don't know if they make that style plug. can anyone please help?




thanks.

 

i talked to denso and they are clueless, so i am really in the need of some help.





thanks.

 

I dunno but here is a 'bump'
