A3 Head Question

DaveTMember

Long story but come to realize I have Aluminum A3 heads on my car. I have read some great posts on here and learned a lot but one answer I can't seem to find is regarding the spark plugs. I want to make sure I'm using the right plugs. My concern is the length, if the spark end is in enough. If someone can tell me what plugs they are using with these same heads I really appreciate it.

Also I'm looking for a Motorsport Edelbrock A331 intake for these if anyone has a line on one.

Thank You

Dave

I have the A3 in all my cars, yes some have the Autolite # 3923 and some have the ACDelco 41-629. No reason for the difference other than I just replace with the same as I take out so it seems both will work. Remember cool heads & just snug along with some anti-seize.

Hopefully a pic of my carb build will come thru.

I generally run my car in open road races ( 150 to 180 MPH), so my carb. specs. are set up for that situation. Your requirements will most likely will be different.
