Cool... Thank you for your response
Saw a set of 06 heads but wondered if they would fit my 01
06 and up heads will flow a little better and they came with beehive valve springs so they can accommodate higher lift cams. If you can score some 103 heads with ACR's, even better.
I don't think you're going to see those gains, I'm sure one of our members who have shops will be along with some data.
Don't know what kind of engine work you have but unless there was a specific reason I needed to change heads, I'd save my money and get a set of aftermarket cams if you don't have any or get my existing heads ported and polished.
Not enough bang for the buck to justify the expense of buying a second set and an intake manifold plus labor. BUT if you get a good deal and are able to sell your take offs, plus do the work yourself
