    Hey good video! I always thought those Ford heads were asking a lot for the money. We know that Trickflow Twisted Wedges and Hi Ports are near that price and will outflow the Z304 heads by far. The AFR's do the same as also. You look like the guy from Coast High Performance. Not sure if that's you. Anyways would like to see more of these SBF and LS and LT testing if you have time.

      Yes sir, TFA and AFR for the win! LOL, that is me, I left CHP years ago and Vigilante Performance is my company. Might do more testing in the future, now focus is on our cylinder head and engine builds.

    The old Canfield heads would flow in the 330's with a little work. The Z heads should easily get there as well but I agree....over priced. Typically "porters" castings are cheaper to allow cylinder head shops to finish them and make a little profit.
    The AFR Enforcer castings are imported. Their US castings are slowly coming more available now but they took a big hit when Edelbrock shut down their casting plant in California.
    TrickFlow High-ports are still my favorite.
    The ProFiler and Brodix ST heads for more budget oriented builds and have plenty of room for porting down the road as the build progresses....as they always do.
    Cool video! Lots of good info and video angles to see the pertinent details!! Thanks for that!

      Yes, the Canfields can flow a lot more with work and same with the Z304 which now the customers wants to do some blending to. Video was just to show how overpriced the Z304 heads are for the brand loyal enthusiast.

      Where or when do you think I can buy a trickflow box intake? Trickflow took them off the market over a year ago due to alleged foundry issues. You can’t find the damn intake manifold anywhere for a 351w. Been looking used for a long time too. They just got the upper part only back online within the past month but without the bottom I can’t use the intake. Curious of your thoughts

      ​@@timweb1510I've got no good answer for you. I'd suggest you look at other lowers and see if any of them use the same gasket for the upper....or if they are close enough that a little porting will solve any port alignment issues. I'm not familiar with that intake in particular. The only box-type intakes i ever used we made from blown-up intakes...like from a nitrous backfire. We'd take the upper and bandsaw the bottom runners and throttle body flange off and weld our own box together. That way we could put nitrous bungs and vacuum ports where we wanted them as well.

    Ford's Z304 just didn't compare to the AFR 195s.

      AFRs dont use offset rocker arms. at least not the 185. they just use a regular scorpion rocker arm they sell on their website
      what you need is 2 piece pushrod guide plates and that's why AFR and most aftermarket ford heads use them. so you can align them correctly

    • @vigilanteperformance8318

      The Z304 heads do need the offset for the Intake and the 7mm casting helps with valvetrain stability for sure but still overpriced in our opinion.

      All old data was lost, would have to flow on and actually see the runners, short turn, bowl, etc. To give an educated opinion. As we said in the video, there are ways to make heads flow on the bench but does not mean they will make power.

    So for a stock 302 in a street truck. The AFR 185 would be good to go with cam, Intake and exhaust. Or would i need to go 306 for the heads to work well.

      185 is like a 6500+ RPM head a 302

  • @95Sn95
    @95Sn95 Місяць тому

    I don't know for sure I'm not an expert by any means just a guy who sees things and thinks but I would think a raised port on a street car would be kinda a waste of time and money, my theory is with an under chassis header the straighter shot gained from the raised port is somewhat diminished by the added angle on the primary tube... And with the header fitment hassle would make it not worth it. I may be way off and its still better flowing even with under chassis headers? With race car chassis where the header doesn't have as many routing constrictions the raised runner may pay dividends...?

    • @vigilanteperformance8318
      @vigilanteperformance8318  Місяць тому

      While the exhaust port would be more efficient, yes, header fitment can be an issue. The other issue is the valve cover rail is a bit higher so on FOX style EFI intakes, the intake might hight the valve covers or require a spacer.
