Profiler SBF heads

[Mpcoluv]

Has anyone done a build with the Profiler 205cc Windsor heads?
They seem like a good deal but I have never seen any results.

I did the head for Pro-Filer, except for the chamber, it was done by Darin when he worked there.

352 cid
249/254 HYD roller
10.9-1 compression
Sunoco 93 octane
1.360 700cfm carb
1 3/4 - 3" header
Parker Funnel Web (port match and flash cleaning)
33º of timing

575hp@7000
460tq@5400

Chad we were very impressed with the way that 352 with the Profilers dynoed. In fact we ran out of time with it as the dyno shop had another engine that need to be tested. We believe with a clover 1 inch spacer that matched the manifold we would have gained a little more power and those numbers were with the Brad Penn break in oil. With some 5-20 syn and a matched spacer I believe that 590 hp and over 470 tq. was easily obtainable. Chad those profilers are the best out of the box unported 20deg heads I have seen. And the casting quality was very good and everything fit well. Also it made that power with only 33/32 degrees of timing which tells me the chamber is working well. We also used a high port piston as the pierce points are very close. We also dynoed this on Sunoco 93oct. pump gas.

David Vizard evaluated and flowed them as well.

Did Vizard ever do an article or dyno test?
Will the normal valve notch positions work?

I have an engine here at the shop right now that I'm going to dyno test in the next week or so... It is a very mild 408 Windsor, 10:1 compression with a hydraulic roller: 223 223 on 107 .561 lift. It has a Victor JR intake manifold.

David,
This looks like a nicely balanced parts combo. I have a feeling it will dyno out very well. I have had experience of Chads heads and so far he has done nothing - other than impress me.

I finally did some pulls on this engine this afternoon. 408 Windsor, RPM 4 inch stroke and 6.200 rods, Wiseco dished pistons. Stock roller lifters, tie bars etc. The engine runs to 6000rpm with no difficulty and it has about 50psi at idle and 70psi oil pressure with 10W-30 Valvoline oil, stock oil pan with a baffle and stock volume Melling pump..

Running with a Holley 4779 the engine made 510 horsepower and 520lbs/ft torque with a 900rpm idle that makes 15 inches of vacuum. This was with a set of long tube "Mustang" headers and a set of Magnaflow mufflers. 93 octane Mobil gas and 35 degrees total timing. The engine made its best torque with a 1 inch HVH merge spacer but it was nearly as good with no spacer at all on the stock Victor JR intake.

These are really nice cylinder heads just imagine what this engine would do with more cam and compression! I had used the 215cc Chevrolet version for a 454 Small Block a couple of years ago and I was impressed with those too.

You've definitely piqued my interest with this setup. I assume 1 3/4" headers? Can you post up the dyno numbers? I'm really interested in what this thing does down low.

I am working on a 418" Windsor build with some I bought from Chad this spring. I ran into some issues find time to work on it, but its almost done. Well see how it does. They do require an adjustable guideplate. But standard sbf rockers seem to work fine.

Dave you used them OOB? Pro-Filer valves job etc?

Did you use Ford rockers or Chevy?

[DaveMcLain]

The heads were out of the box with an SI valve. I did flow test the head and it was best with a 30 degree back cut on the valve. This picked up a few CFM across the board with the head flowing 255 at .400, 296 at .550 and 304cfm at .600 lift 313 @ .700 lift.

I used a kicked up guide plate for a Chevy that I cut apart and aligned and I used a 1.72 ratio aluminum Ford rocker from Comp.



Headers were 1.750 tube that fit in a Mustang chassis.

Block is a '90's factory roller block, damper is an Innovators West, distributor MSD billet.

[user-9274568]

Your flow is really close to what I get here. The low number are different. But mine is heavily blended. Not sure how much blending the OOB has.

4.060/4.155 fixture/no pipe
.200 154/157/103
.300 217/221/144
.400 268/270/173
.500 292/292/201
.600 303/307/205
.700 311/315/209
.800 313/320/211
.900 315/318/215
1.00 318/318/219

The heads had some hand blending work done to the bowls out of the box and I left all of that alone. I just checked the guide clearances and made sure that the valve job was OK before I put them together with the parts I used. If I would have had more time I think it would have been fun to have tried a dual plane intake like an RPM Air Gap.

That has got to be the flattest torque curve ever!

[Mpcoluv]

Did the 418 build listed above ever get dynoed?
