How much?

I was told buy them at PRI that the head would flow 290-300 out of the box.It will flow more with porting.

Interesting. It says like $1750 on the PDF price list from the main page.

I'm not positive, but I think that might just be for the bare castings, which would mean you need valves, springs and hardware.

They look like a good alternative to the others...

I remember seeing these posted up a while back, they're made by Brodix aren't they?

They better flow 290-300 with a 230cc intake runner.

They are an aftermarket head designed to be ported. You can slap them on the car as they come but its more potential than anything else.

Second though.. No way am i paying 2800 for stage 2 MTI heads

CNB

It seems as if they made this head for larger engines.

Thats what he told me.Bob Williams,he is the owner of All Pro.

Looks interesting... nothing wrong with more options!

I have the flow sheets from Bob. They flow around 290 out of the box, they need to be finished. I think Cartek is the only one that's used then at this time. They are putting them on their bigger engines 427ci+.

Good thickness
Room for 2.15/1.625 valves
Changed plug angle
Room for roller rockers
Room for big porting

Hmm. Derserves watching, imo.

Nice, now when is someone going to cast a large bore block?

We also have a revised set from All Pro last friday. tt intake valve 2.200/ ss exhaust 1.625, revised spark plug locations, and the rockers offset .250. These will go on C5R-454 cu. in. motor after extreme porting and we will put on the flow bench. I also have a set of C5R heads (tt intake valve 2.250) already done, but the All Pro heads sound interesting so compare the two. I will post the result as soon as we done with the test.

TNT,
Sounds like a mean motor.
Be interesting to see the data and comparision.

I now feel like the small guy in the locker room with my little 430 cid motor.

JetVette01

any dyno numbers yet? Would this be too big of a head to have on stock displacement?

Andy@A&ACorvette

The problem I see with these heads is a poor combustion chamber shape. It looks like a standard LS1 or 6 liter head. A better shape with more quench area would be better.
There have been discussions about changing the chamber. The port is good, though. I'm hoping they'll change the chamber.

TNTC5

I know some of the tuners out there are testing them: W2W, Cartek etc.. but they are the testing batch heads. All Pro since then they revised the heads and i got the latest set from them. I compare to my C5R heads and they are many similarities. Also, they have 1/4 thickness all the way around for extreme porting. Again, i can't coment until i have the result, anh from the knowledge i think these heads should bring exel results. C5r heads are more then great, but a lot expensive then stock set up.

#001,
The size does not make it go fast, the combinations that what i want to achieve.
