Buy the later coils and the proper harness for the MSD and you're good. You'll also need the later valve covers as well.
Thanks Steff
Can I use 06-08 valve covers on Eagle heads? Or do I need the 09 and later valve covers?
I just bought one for the early coils and installed it no more than 2 weeks ago. They are not listed on Summit Racing any more. Just the later setup. I ordered mine off of EBay and it was drop shipped from MSD.
If I keep the early coils can they be used when I swap to Eagle heads? The old harness is still available on ebay but it is no longer on MSD site.
Trying to figure out which way to go without having buy things twice.
