Yes, I wanted to go with a trickflow but the combination is around $4500. My stock cylinder head call total air flow said I had to send them in to get CNC was $1500 I bought the valve guide springs retainers was $900 total in a stock head $2300 promaxx head total $2000 and there already CNC the only thing is a 46cc stock is a 44cc. Trying to make 650 to 700. I have 2.3 Whipple Camshaft xe270ah just asking to if anybody running these hands. I found no reviews on these heads and talk to Promaxx about them they said it running for for 18 years with no problem.

The trick flow heads have 10 thread plug holes. A better designed combustion chamber. Better valve layout to combat quench. A 3/4" deck surface. Replaceable cam towers.

You're getting a better head for the money. And who's quoting $4500 to build a set of heads?

The only cost difference between ported stock heads and tf's is the cost of the head.

With both heads you'll need valves, guides, springs. And tf heads don't need port work.


650-700 on a 2.3 in street trim is pushing the blower. You'll want better cams. I hope you're planning on e85 or race gas.

Or here is a crazy idea, you could use a set of 44cc Trickflow heads right out of the box complete ready to go with the 125lb springs and the right cam for around $3200 including cams to achieve your goal.... Oh I know here come the "the trickflow valves/guides are junk" people and I can respect your opinion but the cold hard facts are that you wont find anyone who has installed and tuned more sets of these heads, right out of the box with no issues then me and my shop.

You want an Eaton truck with trickflow heads and the right cam on pump gas making 585-600hp? I got you
You want a Whipple truck with trickflow heads and the right cam making 650 on pump 93? I got you
You want a Whipple truck with trickflow heads and the right cam making 750+ on E85? I got you

You see I put those combinations together on a regular basis and over the last 13 years since these heads became available I have had only one issue related to the heads themselves and I have done most likely over 100 or so of these combinations using the Trickflow heads right out of the box.

Can you upgrade them? Sure, its not a bad idea to do so if you have the coin. Is it really needed? IMHO no not really but for those wanting the absolute best parts they can get sure why not. Its kinda like using mobil 1 synthetic oil in a beater car, it may not really need it but if you have the extra coin why not?

Lastly, for those who will come in here and argue that they "know of failures" for the trickflow heads, especially when it comes to followers knocked off and dropped valves I can say for certain that the majority of those failures are from improper installation or the use of a camshaft that was too big. (You cant use stage 3 PI Cams in these heads but people sure do try because they dont know any better, then they blame the head)

If I can be of any help with the OP aquiring a set of head and a set of great cams spec'd for those heads and your needs please let me know. I will be happy to help.

I personally know 5 people with tf failures due to bad valves or guides. Me included.

I don't know of a single follower problem. I know of 3 bad guides and 2 valves to that had the head separate.

My cams are custom spec's for my truck and heads.

You would think that me and my shop would have had at least one failure considering how many sets of these heads we have installed over the years. And I'm not talking just Lightnings or Harleys here, I do quite a bit of Mustang work as well and alot of 4.6 2V TF head installs and even in that community where those heads are used at least 10:1 over Lightnings the failure rate is pretty low.

Over the years I have seen a few threads or posts about a particular failure and each one of those instances were due to improper installation procedures or using the wrong cam.

Personally I would like to know more about these failures and the circumstances behind the failure, if that is even possible.

Fuck I had a long post and accidentally reloaded the page

@BlowerWhore and @Leeproctor83 are both personal friends. I'll let them describe the failure.

Scott cedergreen who's passed away had a valve head come off. 200 miles after his new motor was running. Tf admitted a part failure and warrantied it.

My heads lasted almost 10,000 miles. Cam specs are 237/239 .556 lift and 114 lsa. Spec'd by Todd Warren for my heads and engine.

I'm not saying every head is a time bomb. But if you're already spending good money, buy bare castings and have good parts installed.

My springs and guides, along with having the head resurfaced was $1100. Add in a set of valves and that's cheap piece of mind honestly.

Thanks for the input
Only reason I was asking is because I have enough funds to do trickflow and they won’t be available till February the only reason i looked into promaxx look good he said they’re using Pac springs and ferrea valve I’ve already ordered them two weeks ago, but like to see how they perform, I can always sell them later once I get enough money for trickflow. I know or the best head you can buy for 5.4
What camshaft do think have the best camshaft where to buy

maybe you should have gone the proven route thru Woodbine MotorSports

If you're in a rush to put together a motor, I'd suggest dropping the word best from your search.

The best cams are custom. Jj on here can spec you some. So can Todd Warren.

JDM and jlp have their own cam sets that are probably easier to obtain and are both going to get the job done.
