I found another set of 340 J heads that have been redone/pocketed/ported/etc for $650 here on Moparts. That sounds like a better price.



Yes, $650.00 for a pocket ported set of fresh J heads with a good set of valves and springs sounds about right.

Keep in mind that your short block is the foundation of your engine, putting money in your short block now is the way to go, you won't see a bigger gain from a street small block than building a stroker. If you ever want step up to
a better flowing set of heads down the road it's an easy bolt on change, nothing as involved as changing the stroke of your engine.

Build the stroker low end now, use whatever the best set of heads and other accessories that you can afford, and make upgrades later as budget allows. Don't forget, a good set of J (or any 915 heads) will make very decent power, they just don't make as much as some other choices that can cost allot more.
