Hamilton offers exhaust porting for $400 and the intake is supposed to flow better than the stock one.

So its basically a stock head opened up? Correct me if I'm wrong, but the war head is a whole new casting, with much larger runners? Factory size valves? Any other variances?

I haven't seen one with the intake cut off but 1 and 6 ports openings are supposed to match the other 4. with stock valves and no porting it is supposed to flow 40% more air.

Per Hamilton, it flows 40% more than a stock Cummins head. So that's about the same as a decently ported head. But it has room to port it well past that. I haven't seen any numbers though.

I was going to do your 3/4" pipe plug porting mod when I found out about the street head.

Sent my head in to D&J and Drew is going to use some $1200 valves. Good thing I didn't buy Hamilton's $400 ones.

Seats, valves, bowl blending and some port work which I assume is on the exhaust is being done. Where I'm at now I should have gone with their 24v head or a 12v War head.

I've beat on a set of $400 valves for several years now.
One thing about the diesel truck market, if you want to sell more of your product, just charge more.

I've been on both sides of the $400 valve argument. The early ones I got were complete garbage (almost nothing was in tolerance), this was years ago, when they first came out. Have since ran two more sets since they came with the heads and they are actually pretty good. No problems to speak of and run hard. Diesel parts are so expensive, I'm sick of it. Hamilton seems to be one of the very few trying to make an affordable part

The valves sourced for a while from Colorado were complete garbage, at least for what I was using them for. I had issues with them but with the new ones haven't seen any problems. Just because it's more expensive it has to be better though, right??

hamilton head
I thought Id upload some pictures for you guys of the Hamilton high swirl head. There not the best but you'll get the idea. I have this head on my 3.0 truck and it works well, I ended up doing a side draft and running the 1.75 exhaust valves and 1.85 intake with some mild porting. plans are to have it fully ported for the 2018 season but I wanted to talk with Hamilton first to see that the max flow is in this high swirl head once its max ported.
