[@richardholdener1727]

I appreciate that

[@reevinriggin3570]

It was interesting how even the HP numbers were considering the fairly large difference in port volumes. I will say that the TW head is deceiving in the fact that the port volume "appears" small. However with the relocated valve, the port is a bit shorter in length and that shows up as smaller, but the actual height and width measurements are quite comparable to the other heads. I was sure the Z304's would do better than they did just from the average of the flow numbers. I guess that's why we don't race flow benches! Thanks Richard for all this work.

[@deanstevenson6527]

2e dont race dynos either. But we need flow benches, dynos, and to re-check ourselves against 20 year old data!

[@robertobetancourt7881]

Hey Richie what is better flow or Compresión ? Thanks🇵🇷

[@andyharman3022]

AFR heads are magic. They were about 5th best on mid-lift intake flow out of these 10 heads, but had the best peak flow, but past the peak lift for this particular cam. They did have the best mid-lift exhaust flow, but not the best peak exhaust flow. But yet they had best peak power, even better than the higher compression Canfield head, and had probably the best average power. Maybe I should get an AFR tattoo.

[@BobbyOfEarth]

I just uncovered a forgotten set of 351 D10E heads off a 1971 Bronco that I had stashed in the garage for 25 years. Guess I'll have them blasted, magnafluzed, re-valved and build them ...then store them back in the garage.

[@richardholdener1727]

[@jimdandy849]

Great comparison Richard. This is the kind of detail everyone hopes to see. I especially welcome your comment at the end about how all the heads perform well enough to satisfy most hot rodders needs, and the down-to-earth cost consideration. Not everyone is competing at the dragstrip. With that in mind, how do you think the budget ProMaxx 180 SBF head would have performed in this line-up?

[@thomasbratkon4624]

I have the Promaxx 180's on my 302 and am very happy with it. I'm going to a 331 stroker now and I really don't need to change much. I have been considering upgrading the cam. Good luck

You guys need to audit a university fluid mechanics class. It'll give you more 'tools' to understand how/why fluids change their flow characteristics. There can be a lot of math to fluids, but just understanding bernoulli's equation and the continuity equation only needs algebra and explains a lot.

[@richardholdener1727]

which guys need to understand this equation?

[@HerrPoopschitz]

No mention of Reynolds? 🤔 Bernoulli is idealized. Intake port dynamics are not. What youre suggesting takes a whole .003 seconds to find on youtube...no need for a uni.

[@rustywater3219]

@@richardholdener1727 I was thinking between you and the guys on engine masters. Not being a troll, just suggesting ways to get more 'tools for the toolbox' and better understanding. Bernouli will explain the interrelation between port velocity and pressure, and continuity equation will relate cross sectional area to velocity. There are other ideas like headloss equations and discharge coefficients and yes Reynolds, but they get a bit mathy.

Awesome video! Loved seeing these tests in the old MM&FF and others back then. I do have a question though. Did you ever try running 1.7 rockers at any point with the 274 HR cam with the 333ci? How much would that effect the duration and lift? I actually have a nearly exact build about to go in my 86 GT, 333ci with 274hr and 1.7 rockers, AFR 185 Outlaws( I think same except emissions) and a TFSR intake. Curious how much difference the 1.7s could make...

they add lift, about 2 degrees of duration-sometimes add power

@Richard Holdener This is probably a question you've gotten a ton, but I'm going to try anyway. I have a stock low miles '92 5.0 that I'm going to do H/C/I. I plan on using your favorite Comp XE274HR cam, and probably a well ported Explorer upper/lower intake. My question is regarding heads. I would like to go with something like an AFR #1450 (205cc intake port). However, AFR's own literature about the AFR #s 1399/1402/1472 (165cc intake port) says: "They feature 100% CNC ported intake, exhaust & chambers, A356 aluminum castings and high quality components throughout, in addition these are the only AFR heads that are compatible with the OEM piston valve relief." Is this true, or are the AFR guys full of it? Will I have to have the pistons fly cut or replace them to run anything with a 2.08 or 2.02/1.60 valve combination? I assume you've tested a bunch of these so you'd be one of the best to ask this question. Thanks in advance. Brent

[@richardholdener1727]

@@richardholdener1727 Wow, I got a reply with some GUSTO - and FAST. Yeah, the reason I was thinking "big" on heads is I'd like a head to work on something a bit "spicier" in the future (stroker and/or boost). I do realize the 165 is an excellent head, particularly for a stock 5.0 short block, but it would be nice to not have to buy 2 sets of heads....kind of along the same lines as how your "favorite cam" works well on such a wide variety of applications.

When do you need to start considering race gas in this kind of combination, or in 351 Windsor? At what compression ratio do you typically need more octane than pump gas?

[@blueovaldude]

That is a very common question people have . Too many variables for a blanket comp ratio. Your camshaft makes the most difference. Static compression and DYNAMIC compression matter . Run both specs on a calculator to see where you are. The general consensus is 8.5 to 1 or under dynamic compression or under 180psi cranking compression is pump gas friendly. I have a true 10.55 to 1 in my Windsor on my channel on pump gas , i have pretty large cam specs though.
