[@jarvislarson6864]

The afr will out perform significantly...much better flow & port velocity across low lift to high, peak hp may not differ alot between the two but afr will make more useable power across rpm range. Bet

[@andrigtmiller]

The air temperature and relative humidity of the air matters in terms of the flow numbers. So does altitude, or better yet barometric pressure, which gets lower as you get higher above sea level. I believe what they machine is doing is it is calculating Standard CFM, which means it's adjusted for the air temperature, relative humidity and barometric pressure, giving you a number that is comparable at sea level with a standard air temperature and relative humidity, which I forget exactly what those figures are.

[@SenorYuk]

The new casting looks SO much better.

Question, why flow beyond .650"-.700" lift when most cam lifts are no where near 750-1000 lift?

[@nashvilleoutlaw]

Because it tells you how stable the flow is. Some heads drop off past a certain point where others, flow may dip down and come back with avengeance

On top of the 582 we are building, which you are doing the BB3 363 heads for. We also have a 383 that we are finishing up for our cruiser. We went with these AFR street CNC heads and a .583" cam (w/ 1.6 rocker correction). Great info, I was surprised to see the AFR's had a lower exhaust port flow. Exhaust flow is something they seem to do extremely well. However, it makes sense with the Profiler's raised exhaust ports.

Hey Eric.. Can you do a set of factory Gm Fastburns vs AFR 195'S??? All you would have to do is flow the fastburns, i am told they are right with AFR's flow numbers...

[@Parents_of_Twins]

AFR rock on the exhaust flow numbers which I believe are a lot more important than a lot of people think. No idea how they relate to any factory heads however they generally perform near the top in cylinder head tests for power production.

[@ICONBADGTA]

@@Parents_of_Twins Yeah they are top, those profilers are the best head going now due to flow and price. AFR has priced themselves out of competition unless their "AS CAST" head will flow 270+ but that would have everyone buying them and not buying their "CNC STUFF!! @Eric Weingartner Do you think a cartridge/smoothing roll clean up or smoothing on the profiler would help flow any? Maybe 5cfm across the range?? If so it's got AFR beat!

[@rightsidelanechoice7702]

Why would the race bowl have the wing or vein angled toward the shrouded side of the valve. It’s angled toward the open side for a reason to create more velocity to the center of the combustion chamber.

[@flinch622]

Not my specialty, but surface finish on a casting seems to be a function of two things: grade of casting sand, and the release agent used. Whether somebody figured out a better process or regulatory changes made some release agent obsolete, I have no idea. edit: Those profilers... those exhaust bolt locations make me think of a 1470 gasket more than a 1406. Can you confirm which is closer? Thanks.

[@frankiehollowell779]

What would happen if the runners were worked on the profiler simialer to the afr's

[@gregmcnamara2563]

The difference in casting finish is due to different casting technology. Sand cast (Lumpy, larger variances, slower production, and more expensive) versus investment casting such as lost foam casting (Cheaper, more accurate, faster, better surface finish, less machining). It enables them to produce more complicated castings with internal passages etc, with greater accuracy and no core shift. Almost all engine blocks, heads, driveline castings, and industrial equipment are now made that way. Check out some KZbin video’s on it.

[@adamarndt7617]

This was great to see the Profiler-machined Profiler heads vs. my Jegs-rebranded Profiler 195cc heads. Obviously if you get them assembled the components from Profiler will be way better than whatever chinese parts are cheapest @ Jegs, but I didn't realize the difference in how the bowls are blended until this video. The nice hand-made burr bowl blend that Eric showed is WAY better than what looks like some machined grinding of any core shifting that sticks out into the bowl that my Jegs heads had. The Jegs heads were just cut maybe 1/2" into the bowl from the valve seat and that's it. There were some huge lips beyond that that never got addressed AND the machining was smooth. (It's my understanding that this is one of the more critical areas to have a rough texture to keep fuel in solution).

Eric - Pontiac iron d-ports can be ported to flow slightly better than the AFR intake (210cfm @ .300, 285cfm @ .600) yet no one wants to run these anymore and all get Edelbrock, Kauffman, etc. aftermarket heads. Why ? isn't airflow still airflow on a less sexy looking head?

[@magellanstravels]

How do you feel about world sportsman heads that are ported

[@kennethalbert4653]

Seems to me the lesser flow (especially in the useable range), time and extra machining costs with the Profiler justify the additional cost of the AFR. Also, the chamber looks better on the AFR.

Well you could use a cam with less of a duration split on an afr. could probably use a single pattern it looks like. thats what most people who've used them say

Buy the race set, put your $$$$$ into airflow. An engine is a air pump, and yes cfm's isn't the whole story but it's a good start, especially if you have good flow with less port cc. That translates into more port velocity which in my opinion is as important or maybe even more important than flow

[@adamarndt7617]

The Profiler exhaust ports ARE raised a lot, but the REAL problem with header fitment is that the bolt holes aren't centered on the port! There's basically NO off-the-shelf 1 5/8" header that won't block the "good air" at the top of the port with the bolt holes where they are. You have to weld and redrill or slot and fill header bolt holes or just step up to at least a 1 3/4" header with those stupid exhaust ports. -No reason for them not to revise where they put the exhaust bolt holes and just center them on the port so an off-the-shelf 1 5/8" header fits. I love my Profilers, but not having a header that fits anything worse of terribly just because they won't move a bolt hole is just inexcusable.
