Spark plugs for Edelbrock performer heads

[Cobra351]

I did a search, but could not find what plug to run in my 351W.It has a trick flow stage1 cam, Edelbrock performer heads, and gt 40 lower.No nitrous or Blower.Anyone point me in right direction? The directions call for Champion spark plugs.Dont really want to run those.Thanks, Phil.

i can try to help ya. i have performer heads. but there on a 5.0 my directions say to use champion RC12YC. i cross refrenced that to autolite 3924. hope that helps. 351 could be different.

I run Delco Rapidfire #9's (new design) and they work great for me. Never been a fan of Autolite plugs myself. Also had good success with NGK GR5/FR5 plugs too.
