The boys at Patriot represented themselves very well in the test. 420HP out of set of heads that cost a smidge over $800 is not bad at all!

I know the the test was for SBC heads, what are your thoughts on the BBC heads.

I've cammed several projects in the past with the heads and made very respectable power, 750HP 496's on pump gas. They will have castings to machine in August.

I'd not realized that Patriot was a serious player with the small block Chevy. I've seen their heads on modular Fords and Chevy LS engines, but not on the older style stuff. Good to know, wonder if anyone has run them for any length of time to test durability, etc.

I read that article the other day, I was surprised with the results. They were able to make some pretty good power with heads that weren't all that expensive really. Pretty cool.

I've been trying to figure out which heads to go with on my 355 for a while now.

Right now i have some dart iron eagle 165cc/72cc, basically a little better than stock replacement.

I've been thinking of going with the e-streets.

But after reading the article, the patriots are just so damn appealing. $815 ! That's $100 cheaper than the e-streets and more power!

I know any of the heads featured in the article would be a vast improvement. But i think i'm just about sold on those patriots... but then the dart 200cc would be nice if i ever decided to go with a roller cam.... hmm..

Those numbers I see are pretty good. I always thought the magazines skew there numbers to make more money in some way or other. I was always under the assumption that patriots were not that good, or that's what I have heard.

read the test, top 4 were all very close. Within a just a few hp.

In this shoot out, the Dart stayed within 3 (mostly 1)hp all the way to the Patriots 5800rpm.


The Patriot pecked at 420 at 5800, the Dart peaked at 419 at 5800, but Dart stayed above 415 to 6400rpm. At 6000 the Patriot tanked!

Also in the test, they used 1.5 rockers on the iron head and 1.6 on everything else.

IMHO

The quality of the eddy and Dart out way the others 10 fold.

Give me the DART!

The Pat head is 15cc smaller. If one is building a street car with the occasional trip to the strip this head will have overall better throttle response.

If one is building a strip car that will be on the street some then the larger 200cc head would be the better mouse trap.

I validity of that is very very minimal, and if your building a strip car none of these heads tested would be ideal for that application.
200cc is not big for a 355 & up with a hydraulic/solid roller cam.


In this budget build test, I still give it to Dart.

Two engines within 1 hp of each other to 5800 rpm, the higher 6400 rpm engine will run off and say goodbye!

The higher RPM of the Dart allows the shift points higher in gear changes and better power band. They will be dead even till the first shift, then it's all over!

I wish they'd have included more cast iron heads in the test, whether they be Dart or World Products, etc. I'm still a bit partial to cast iron, call me old school.

Dart makes the SHP in a 180cc version. Since everything else Car Craft tested was 170 - 185, I wondered why they jumped to the 200cc Dart. Maybe Dart didn't want their 180 competing with other heads of the same size.

I've got nothing against Dart, I almost bought a set very recently. And I ignored Patriot because they're not made in the U.S.A. But putting all of the patriotic "buy American" sentiment aside, if Dart's going to provide a set of heads for this kind of evaluation, they should have the courage to put their 180's up against the others so everyone would be on a level playing field. I also blame Car Craft for accepting the 200cc heads. They knew it would skew the outcomes but the did it anyway. When I finished reading the article I ignored the results for the Darts because their heads were ringers. I would have been shocked if they didn't come out on top.

All of this, of course, is just my opinion.

Paranoia runs deep, into your heart it will seep, there is a man with a cylinder head over there saying look, you better be aware....

It was a price comparison shootout. The bigger head wins!

Under a grand Dart sent the best head!

Dale's AWB Dart had Patriot heads on a 383 SBC built 4+ years ago; it's driven and raced all over the world, and I don't think the heads have ever been touched. They were complete from Patriot with standard parts--no upgrades.

From that perspective, okay. However, I would still like to see how Dart's SHP 180 would stack up against the others that were tested here.
