32 valve heads

Here is an sbc artical showing a diffrent arao rocker system being used, also some of the standard valvetrain parts from the sbc version can possibly be interchanged like valves, exhaust rockers, swivle feet, springs, retainers, valve covers, rocker shafts, bases and a few other parts with the sbf versions.



This is the standard 32v sbc valve train version.

Some of you may have seen a 32v vid clip of a sbc 850hp blown street rod engine from NRE, these heads look trick with a 671.

and another 815hp n/a sbc 32v version some may have also seen, there are a few other 32v vids on YT also for those interested.

A friend of Hals sent me some pics of the last 2 pairs/sets of sbf and sbc heads he got from Hal from Dominion Perf this last year. Hal was sick for a while and passed away recently last year so no more Dominion 32v versions are available now, RIP Mr Carlson. The sbc cast versions I understand were all cast at a local cali casting company.









Hal was a ford guy and only did the sbf versions in billet aluminum, Hal was working on these unfinished sbf ones moding them for a Boss 302 type intake and is why I wanted to do my sets the same. With billets you have easyer/more options for doing mods.

Here is an old sbf mag tech artical copy Hal sent years ago.

As you can see above, the pricing ($3500 to $4900) on the 32v Dominion Performance versions was reasonable for such custom made parts.

For you bbc guys, I do though really like arao engineerings 32v BBC versions, I love there high port design on these heads. I would LOVE! to see a 32V SBF version designed like these.

Now that would be a challenging header project. .

I agree this isn't going anywhere, no one is asking an engine question. I'm more interested in it ending!

If some of you 2V guys are upset about this 4V thread, you can easily put me on you ignor list as I did say I was going to post a bunch of info I have in this thread for those interested. thanks.

Northstar, the Thunder power bbc heads also have a simular design though I am not sure how much better it is than just a standard type system.



The 32V Thunder Power valvetrain differs a bit, though again they use a porsche type valve adjuster.



Arao had a simular sbf billet version exh setup in the past, I dont think it made more power though.

Dominion/Hal knew how to make it a p.i.t.a if you wanted to buy a lower stage head and then mod it your self. Got these modded to a boss port for big ci, good thing its a billet lol.

Just a few pics of FORD's own prototype 5.0 32 Valve pushrod heads displayed at an early 90's trade show just before the new design 4v modular engine came out.

That's beautiful.

Feuling also had some prototype chev/ford multi valve pushrod heads in the past with I understand simular valvetrain layout to the sbf design.
