    HeadGames Motorworks offers N54 cylinder head services

    Some of you may have read Headgames posts regarding S55 head work in that forum section but they also do N54 work.

    You guys can ask @HeadgamesDave about the gains and pricing but as we all know there is quite a bit of room to improve the N54 head.

    Why not? How is someone going to justify the purchase? Will you guys provide gains or any data?

    Head porting without flow bench testing is irresponsible.
    Head porting without sharing flow bench before and after is unmentionable.

    Pretty ports don't always flow better. IDK, prove me wrong.

    Emailed asking for more details, pricing, etc. Promptly ignored. So you are porting a head for the N54, won't share flow numbers, which honestly is no biggy, but what are they testing it on? A Ported head show the best results when the parts around them are also upgraded for increased flow. Throwing a ported head on a stock turbo N54 isn't going to show much.

    If anyone is interested, we will be paying Rebello to flow test a stock head, against our ported heads, and also against the ported N53 head we purchased and should have soon.

    very odd not sharing numbers. So if someone buys them, doesn't produce increased numbers you can just say "oh different day, different dyno", "bad weather", "bad turbo", "bad gas" and so on. The list of excuses is endless.

    You do realize head games has a long and successful track record, right?

    You're going to get gains from proper head work regardless given the n54 head flows terrible from the factory. Still sharing numbers is part of the game. Seems like either you get a company with good work and lack marketing skills or vice versa.

    Pretty shady not publishing head flow numbers while asking for money. If I went out and wanted to get a set of heads for any domestic vehicle the flowsheets are publicly available for just about any offering I can think of. So it really isn't something outlandish to expect flow numbers for something you are going to be putting significant coin into. I'm sure they publish their prices so might as well see what you're paying for

    Sometimes the numbers are confusing.

    When comparing stock ports to ported, usually you see-
    Stock ports flow better at lower lifts, Ported flow better at higher lifts.

    So if their flow numbers show less flow at the first 50% lift- Everyone will dog them and they will lose power and TQ at lower lift/less throttle/drivability.
    Then if their numbers show better flow over 50% lift- Everyone praises them and they make more power at WOT/dyno.

    If the ported heads flow better at lifts higher than what is achieved by the cam, that is worthless.

    a well shaped port will have plenty of velocity for low lift flow figures, I agree the some hogged out ports that are not properly shaped will only pick up in higher lifts but if you're a professional you know better than just making it bigger to get the flow

    This is perfect Marty!

    We don't share our numbers because it's so confusing for the novice guy to figure it out. Even for me, I flow something and look online to compare sometimes and it's super difficult to read and decipher it because of how it was flowed. There is soooo much that goes into this. We are not racing flow benches.

    So, a guy could be looking at our head with stock size valves, and a non- hogged out port and take the flow numbers (if we provided them) and look online and find a head that was ported and it flows 330@.500 while our head flows 290@.500. Most would think that the more flow is better! But, for 700whp this head is slated for the bigger head would NOT be the one to buy. (these numbers are for demonstration purposes) in-fact it would SLOW the car down! Because it might make more peak, just like the bench but it runs like poop anywhere else in the range.

    We port with area under the curve in mind. And, we don't share numbers on any genre we deal with. You can call that shady, or bad marketing. But, the real shadiness and bad marketing is in inflating numbers or giving your numbers that don't have any relevance to your application but saying they do.

    Our cylinder heads have shown what we have learned on the bench. We are not paying someone else to flow them. We are not a shop that works on turbo's or cars or parts and selling a head. Cylinder heads are what we do! That's it!

    I do not think that is in question. I think the dilemma is if you are going to sell a platform on a product, you have to show some sort of results right? I mean I guess not everyone, look at DocRace and that intake manifold, but I digress. Either post before, and after flow numbers on the head, or before, and after dyno numbers. When asking someone to spend what I assume would be close to $3000+ this should be standard...
