Re: Speedmaster Heads ?

Jim aka Bird Dog454, I got my CNC optioned 294 RR's from Wolfplace 2 days ago, I looked at the link you had on the speedmasters and had to chuckle, add $300 and call Mike Lewis

Funny some stuff from china is good just because you sell or has bought a set
I have a LOT of chinese stuff but when it comes to BB cylinder heads I try to stay with a Us casting I have seen How good the speedmaster casting is and not impressed of the stud bosses, Chambers etc.
We sell what we trust and stand behind. I've had the Speedmaster castings in the shop. Had several heads in the shop. Don't sell it even though I can buy it cheaper.

Last time I looked a Daytona Sensors system that includes the coil is cheaper than an MSD box. USA made for less.

I like Apple, don't like Samsung. Don't sell either.

Why is it we never have time or money to do it the right way in the beginning but we always have time and money to do it over again?

Doing it once is cheaper than doing it two times.

Decent nrs!

If you see this Mark a couple of questions how much more does your 781/049 heads make? If you compare with brodix race rites or edelbrock rpms would they be close to your 781/049 with some of your work to them?

So you feel the oval pro comps are better than the rec 320 cc version? Seems like the ovals made almost as much power as the recs with much more cam.

Thanks Much for posting that video link! It explains a lot (less $ up front, more on the backend in re-work and also the design seems to be off abit)

34% of my truck was hecho in Mehico, 64% made in USA and they didn't state where the remainder was made. This was on the Maroney sticker.
Even though a modern fuel level sender is made in the U.S., the pump inside is imported. Other parts are hiden in assemblies.

Re: Speedmaster Heads ?

That is still some money when you still have to fill them. My guy just got a set of Flotek heads for just a smidge less. They are ready to bolt on just have to install springs as he had the spring for his cam. That is valve job and US valves not the Chinese stuff.

who did you get the flotek heads from? I'm a little confused with your post, were they bought as complete assemblies or bare?

How Do they compare to brodix race rites or edelbrock rovals out of the box or with your work to them? How Do the race rite and rovals compare to your 781/049 All with your work.

Hope Marks comes back to this thread and answer some of my questions.

According to the Brodix website, flow at .700 is 320. ProMaxx is 389. The BB-2 is relatively old technology. I understand your loyalty to U.S. products but I'm not giving up that much airflow just to buy American.

I've looked at a lot of knock-offs but haven't seen any quite like these. According to tests, they aluminum is plenty hard and I have measured to determine that they're very thick. Valve job/location is on par with bare Brodix or Dart out of the box. They weigh right up there with the good American made stuff, nothing like ProComp that are 6-10 lbs lighter. Flow numbers are very close to what's advertized on the website.



Everybody has their own money and budget, I buy the best I can within my budget.

Re: Speedmaster Heads ?

Were they measured on the same size bore?
I know my old AFR's #'s were flo'd/tested with a I think it was a 4.1 something bore and a 1-3/4" pipe so when they were on my 355 they would flo less then when I put them on my 406 correct?
Just curious no dog in the fight.

Re: Speedmaster Heads ?

Mr66. I was told these semi assembled heads from speier racing heads. Heads have there valve job with there valves with some chamber work and since he has his own springs retainers and locks those are that is needed to bolt on. Speier racing heads did all the work to bare heads.
