64.12.116.130 The BBF Cylinder Head Pecking Order
No score for this post September 27 2005, 12:33 PM
Mike,
We've done this before and I think maybe somebody put it in the Engine Build Section, but if not I'll go over it again.
It helps if you divide all the heads into four major families. The four families are;
I. Hemi Heads;
top to bottom the order is;
1. B-441
2&3 (tie) A-441, and the billet Indy Cylinder Head Hemi
4. Original Boss 429 production heads.
II. Pro Stock Wedge Heads;
Fords FRPP C-460, D-460, & E-460 heads. Also Profiler's C-460 Replacement head. TFS's B-460 Bastard Pro Stock heads, and the Blue Thunder Thor head belong in this family. The pecking order is debatable, and certainly the size of the engine that you intend to use them on comes into play here. I'd suggest that the order from top to bottom may be;
1. Blue Thunder Thor for big inch wedges 650+ CID
2. E-460 FRPP for NHRA Pro Stock
3. D-460 FRPP
4&5 (tie) C-460 Replacement head or FRPP C-460 are on the same level.
6. TFS B-460 Bastard Pro Stock heads
III. A-460 Heads;
Original TFS and Ford Motorsport heads, also the new style TFS A-460 heads, the Eliminator 900 Series A-460, and the EX 514 heads. The EX 514 is available in cast iron also. The ranking on these heads is again debatable but I'd say at the top of the list we have a 3-way tie with the;
1,2,&3 New style TFS A-460, EX514 and the Eliminator 900 series.
4. The older TFS and Ford Motorsports A-460 castings.
IV. The standard Ford Production Heads;
In this family we have several heads including both cast iron OEM production and aftermarket alum. heads. I'd suggest that the pecking order would be;
1. FRPP Kaase designed SCJ and the soon to be released Kaase designed P-51 head.
2. The Blue Thunder "B" head which is the one with the raised exhaust port and the Chevy style flange pattern.
3&4 (tied) Blue Thunder with the raised exhaust port and Ford bolt pattern, and the TFS Street Heat head, again with a raised exhaust port and Ford bolt pattern.
5,6,7,8,9&10 Big log jam here, but we have the old Ford A-429 heads, the Blue Thunder CJ head with standard exhaust port location, the old style TFS CJ head, and the three different versions of the Edelbrock RPM/CJ heads.
11,12&? We have the cast iron production DOOE-R CJ head and the DOVE heads along with others such as the Police Interceptor head and etc. I am not saying these cast iron heads are any worse than the big batch of alum. heads I listed right above. They just heavier!
Probally more importantly than the pecking order of the heads is who you choose to do the valve job, the porting and flow testing of the heads. In other words, the quality of the work. I have a seen good quality Blue Thunder "B" heads outflow poor quality EX 514 heads for example and they are in two different families. What I'm saying is, a head that is lower in the pecking order, can surpass a head that is above it due to being properly prepped.
Hope this helps,
Charlie

you seem to be very knowledgable on the subject Are the aluminum CJ heads better (other than being much lighter) than the iron? What are the pros and cons on using CJ heads. Was also wondering what all the prefixes mean A, C, etc? Thanks

the alum. heads are better than the cast iron heads, because all the alum. heads have a better exhaust port. They flow more because they are designed better. IMO any cast iron OEM production head needs serious help in regards to the exhaust flow. They are "choked" from the factory. There are several guys who are good cast iron Ford head porters. Three that seem to be working miracles that are on this 385 Forum are Bret Powell, Scott Johnston and Scott Vincent.
The intake ports of our Ford OEM cast iron heads and aftermarket cast alum. Ford heads are much closer in parity than the exhaust ports. Nobody needs to make any apologies for our OEM cast iron intake ports. They're good! Especially the DOOE-R CJ head.
As for the letters A, B, C, and etc. This is just Ford's nomenclature for distinguishing early or original versions of parts from later versions of parts. "A" is generally the first version of a head and then "B" is the second, "C" is the third and so on. Most always the later versions have some design change/upgrade in order to imporve the part.
For example the first Pro Stock wedge head back in the early/mid 80's was the A-460, then we had B-460 heads, and by the mid 90's we had the C-460 head, then D-460 and the current NHRA legal Pro Stock head for Ford is the E-460 head. That's where we are at now. Maybe Lem or Gary Blair can give you a better answer on this than I can.
Hope this helps,
Charlie

216.207.70.45 The older C and D-460's had the valves spread .030.
No score for this post November 3 2005, 9:06 PM
Some valve guide failures and subsequent cylinder wall interference on smaller bores caused Ford to move the exhaust .030 closer to the intake.
The older head can accept a 2.520 intake valve. You can use a later C-460 and move the guide and seat over as well like the older head.
