that head looks pretty interesting ! please keep us up to date with your work on that. those look like something i can afford to play with on my own after i pay the docs and hospital every month. what kind of torque [which i am mainly interested in, letting hp fall where it may] and hp are you looking at achieving, and what application ?

Hey I got a free shirt when I bought 3500.00 worth of nitrous stuff two years ago. At least I got some use out of the shirt. By time I get my car running with the nitrous I will have the shirt worn out. Lol

Does any one know if there is a Chinese version
of a alum W-2 head.... the only alum W-2 that I
know of is from Indy at over $2000

Hahaha,
that's funny.
sounds like a few of my projects over the years.


I talked to Todd again today. He has the heads in.
I chose to step it up.
Going for the $1000 full port workup from his head guru over at Flow Tech 2 on fb.

I will have a couple serious questions to pose to a few of you that can make a stockish shortblock stay together at higher HP levels.
Might be getting myself in a little deep with all these new parts.

Guess I need to make a new thread for that.

Also, a few pics don't do justice to the speedmaster head.
I'll have to make a video.

One thing I noticed the $260 bare ebay version looks like straight plug and these are angled.
Also the ones off ebay do not have any intake/exhaust entrance port work done to them. Not even sure what I bought for $120.

The guy said he has had the head for a year supposedly.
Maybe it is an older version of the procomp?????

Need to take some measurements of seats and cc the runners.

I was planning to get some chinese heads, blend the bowls, match intake, and install the P600b procharger.
Looking for 500-600hp

Now I've got these 300/230cfm ish heads coming down the pipe along with a 78/75 billet T4 96.ar which I've seen on Youtube make 750whp.

So I have no idea. 650-700whp?
All depends on what transmission I end up with. Lock up or not.
And whether or not it will stay together.

Hmmmmm,

I just checked the description and the Guy I bought the BB chrysler head from said this was the exact item
he bought a year ago.

are you building a small or Big block ?

Small block, Diamond dish pistons, eagle rods, TS piston rings, main studs, and
stock cast crank balanced for new parts.
Did a calculation yesterday of my bobweight and came up with 1923grams.

We'll see how far off I am when I get it back from the balance shop.

Found the proper head description after taking some measurements.
This is actually the link.

Angled plug head. 210cc/70cc


Weird thing is it says 2.10/1.81 valve size.
Im measuring 2.07ish/1.78

May have to buy me a propper sized set of these. 😳

What is the advantage/disadvantage of angled or straight plugs?

I'd like to one day use my stock 68-70 hp manifolds flipped for a TT setup.
Guess I need to run down and grab them to see if it's feesable.

Thanks for all the positive input from dizuster and others for this project.
I just re-read this thread and there is a lot of good info I breezed by the first time through.

Very Inspiring!!

Angle or straight plug?

The first time I heard of this was in the early '70s when the Trans-Am series was big and American V8s were racing in camaros and firebirds and mustangs. There was a lot of factory support and people like Smokey Yunick consulted with the factories, so there was a lot of dyno work done. One of the areas being looked into was the combustion chamber. I don't know if it was always known, but there was power to be gained by moving the spark plug closer to the exhaust valve. Given the layout of the smallblock chevy, the only way to get the plug closer to the exhaust valve was to put the plugs in at an angle. People were actually machining cast iron plugs to press or furnace braze into the plug hole, then drilling a new plug hole with a milling machine. I think the angle plug was worth about 25hp on a 5 liter chevy. At some point chevy high perf heads were available over the counter with angled plugs.

How this applies to Mopar heads I don't know. Smallblocks already have angled plugs. Bigblocks were designed with straight plugs. When Edelbrock brought out their head the plugs were angled. While this probably made a power improvement, it also made some clearance problems when used with headers designed for straight plugs. Some in the Mopar community breathed a sigh of relief when MP's version of the Edelbrock head came with straight plugs.

R.

Did a quick video on the angled plug head for use with stock
68-70 HP manifolds.
Not gonna work.

Criepy's, no sound,
first time to add video directly from youtube app.
That didn't work either.




Made another WITH SOUND.

Here is a port/casting overview of the speedmaster Chinese 210cc angled plug head.
Closer look.

This guy is talking about a 200cc ProMaxx heads top quality combustion chamber design. (chevy)

It looks about the same as the above Speedmaster to me.
Nothing impeding the flow straight out of the valves other than a very small ridge, plug hole protrusion, and possible deshrouding depending on head gasket size.

Question to @atracingworld-usa on ebay:

I bought this just to check valve concentricity and/or to widen seats on the exhaust side. Maybe it will actually work for a valve job.
2.14/1.81 sizes.
Seems legit, or not. lol

80 hrs labor on some Promaxx heads.
Valve guides super tight.


I'm almost done watching every video this guy has posted.
Taken me a few months to get through them all.

Google- Headbytes Porting reviews -the guy that did the videos you posted.

yeah, Yeah.
Everybody's got problems.

There was lots of good info disseminated sparsely throughout.
Truth is truth.

You ever watch any of these excellent videos?

Dude got busted for drugs and sexual assault charges.
Doesn't mean the info presented isn't some of the best on youtube that I've found for DIY turbo builds.

Cars run pretty good too and shows how he did it step by step.

This headbyte guy's a fraud and a cheat...ask a real head Porter about his work...the laughing never stops.

He's so successful he works out of a garden shed.
