Yes, SpeedMaster Known for the $89 small block, duel plane, duel engine airgap style intake manifold you see on ebay and swap meets. Did you know they made A LOT of stuff for Mopars and they are not China parts, But America and Australian made? Seems like unaffordable choice for street cars and possibly race as well. Going to look at a set of heads for my budget 360 street motor, but wanted to see what people's experience on here was with them.

Pro Form is a Chinese company owned and operate by them, Speedmaster is an Australian company that either got bought by Pro Form or they bought Proform
I have bought several sets of their Speedmaster CNC BB Mopar heads, I'm not using them yet Soon

Speedmaster heads aren’t made in china?

I thought April fools day was over a week ago.

I think PBR has bought several sets of their heads.
I just bought one of their intakes for the 340 Valiant project, and it looks good.
About 1/3 of the price for an Edelbrock, so I figured it was worth at least checking out.
I generally avoid Chinese stuff if possible, but in this case the wallet over-rode morality.
In my defense, the other 90% of the expenditures for this deal are US-made stuff.

Yes they do have manufacturing in china, the distribution enters are in us and auzie land. Guess I read their page wrong,, or they made their page look like it was not chinese made products. Either way, still like to know I anyone is currently using their stuff or has used their products.

My assessment would be that for the most part the Chinese heads have gotten better over the last 5-10 years.
I get them(Chinese heads) in the shop for a look over and/or some tweaks fairly regularly.
It’s not often I come across something bad enough where it was likely it would have caused an issue down the road.

Of course, if no one looks at them, then it’s a crap-shoot……… and something like this gets missed.
This was particularly poor seat machining, which would likely have become problematic had it been left like this.
This example was a SM RPM style BBM head(which I haven’t seen them offer in several years).

Well $800 bucks lighter in the wallet, I have some heads I can run on that little engine. Probably have the shop check them, just in case.

I’m about 90% sure you will like them. I’ve touched and ported over 15 sets so far and have four more set’s sitting here waiting to be ported. Edelbrock guides I’ve found to be a hair on the tight side to my liking. Speedmaster heads are a touch on the loose side which I like. I did find one intake guide that was .003 over so I changed that one. You will probably find the valve springs are set up to lose so check that out. Valve job is your typical basic valve job. Lots and I mean days worth of reading on forabodiesonly about these heads pinned in the small block area. From flow numbers to porting tech.

Marsh performance sells them with better valves and springs

good to know, thanks.

I have a set of their assembled heads and stainless rockers going onto a stock bottom end budget 360 build for my wagon. Hoping to have it running by late May, just waiting on some parts right now to finish the motor.

I had their air gap copy manifold and returned it after reading it leaves close 30hp on the table compared to a real air gap...Ended up with a single plane instead for my build, but some parts don't justify the savings benefit in my opinion. I was going from 318 iron heads with 1.77" intake valves that I sold for $300 local, so the $900 for the assembled Speedmaster heads were a no brainer, and so far on disassembly they have checked out okay.

The Speedmaster intake is a dual plane basically copied from an LD4B on the bigger runner LD340. I ported one and it was ok but I personally would never run on except on maybe a very mild street car. I bought it during the 40% off Black Friday sale for my son in Colorado but sold it after I ported it. To many better intakes out there. If you got your heads for 800.00 you got a good deal this time of year. They are around 1190.00 off Speedmaster or summit. I paid around 733.00 a pair for complete heads during the sale.

It was a Facebook market deal. Guy had a falling out with a rooked machine shop and was unloading his unused parts. He gave me such a deal, I got him info on some parts he couldn't' find to finish project.

PBR, what kind of flow did you get out of the intake ?
I'm putting it on a .030-over 340 in a '68 Valiant that still has J heads - will upgrade later - in a relatively mild street/strip build.
Heads on the thing are probably fairly weak, 1.88 intake valves, cam is 233/240 @ .050, .474 lift, on 110 straight up.
Converter seems to be a bit above 2500 stall.
It's getting my old 750 DP, 4.10s & 255/60 drag radials - no more room until until the manly tools get put to use.

PCE in the part number is Pro Comp products right? I built a BB Chevy w/ a set of the Pro Comp 320 cc heads on it. They hadn't been run very long before I went through it, but it had some severe valve guide wear. Soft materials.

This is going to be a little confusing as when I posted this on forabodiesonly years ago I explained it as I went along. One of these tests were done along with my sons old style Torquer intake. These test were done on a stock set of Speedmaster heads and a slightly ported set (280 cfm) try to follow the notes above the tests.

I have used the head castings they look good to me; in fact I think the castings may be better quality than some USA made heads. I then buy good valves and springs, never had a problem.

OK, thanks PBR, seems clear enough to me.

Almost everything they make is a copy (ripoff) of something a US manufacturer designed and made. I don't support companies like that, because it hurts the companies that put in all the R&D work to bring the original part to the market. How would you feel if you put a lot of time and money into making a product, just to have someone copy it in China and sell it as your competition for less money? This video just got posted a couple days ago about a valve body design they stole.
