Eddy spark plug recomendations

[hypermite]

I haven't bought spark plugs for my Duster 440) yet, Edelbrock calls for small block plugs. What brand & part # (for those who have the Edelbrock heads) are you using ???? I've got the 84cc heads & 10.3 to 1 compression, if that makes any difference.

i'd start with the heat range plug that came in the 340's back in 68 or 69 if you motor is hopped up like the factory did back then.

you are suppose to use 14MM x 3/4" reach gasketed spark plugs, they recommend Champion RC-12YC. I use these plugs and do not have any problems with the heat range.

Use some with anti seize slobbed all over them.

That right, make sure you use some type of anti-seize so you do not hurt the threads inside the heads. Thanks StrokerScamp

Thanks guys, That's the answer I've been waiting for. I've had bunches of FWD Mopars with alum. heads, so I know to use anti-seize, but I DO appreciate you guys watching out for my backside too !

Remember too remove them cold. If you remove them hot, it might not matter that you have anti seize on um. lol
