Hey guys, I was wondering what you all thought about these heads.

If you disregard the $6K price tag, (or if you are super rich) would you get these heads?

They flow 375cfm, are these heads better then otehr reacing heads?

Money not a factor, are they better then other heads?

they remind me of the old dominion 4v heads

No. Those heads are for people on the internet to talk about and fight over.

Pick an ET or horse power number and you can find 1000's of guys that ran that number with good old fashion inline valve heads.

I don't know anybody that has actually run the 32 valve head. I could imagine the conversion is probably a nightmare! And would cost a lot more then 6k by the end.

They can claim all they want with the head but there are many other conventional cylinder heads out there that will out perform those.

Victor Sr, Brodix Neal, and Yates heads are just a few cylinder heads that would be much better then the 32 valve head.

For a good, full out race cylinder head with all the best components, you will spend around 10k.

god damn, $10K [Eek!] Thanks a lot guys.

I guess in theory they sound good.

I think I would still be interested in seeing someone actually using them. Like dyno charts, with these heads, Victor Sr, Brodix, and Yates heads all going against each other. That would be sweet.

Thnx guys

All of these are great heads that can all make around 900hp NA with the proper setup.

If you are class racing then rules may apply to you. Like the Neal heads are a canted valve head and are often not allowed in the slower, "street" type classes. And the Vic Sr head is an inline valve head.

The price for true power is not cheap!

I once talked to a guy that had the 32 valve heads he was happy with them and said the work to install them was very minimal since the 4 valve design still uses a in the block cam. He said the difference between his tfs stage 2 heads and the dominion heads was over 100hp but this is just what he said i have no experience with these heads

Anyone ever seen those rotating valve heads in action? A buddy of mine linked me to their page a while ago, and it seemed pretty cool.

more valves = better

how fast is the fastest 2 valve/cylinder head? 4's? the fastest 4 valve is what? 7's ?

Apples and Oranges, dude.
last time i checked, the 2v, 4-second guys were running 500 cu. in. big block motors with MEGA boost and 3" valves, not 281s or 302s with 1.6" valves. you cannot fit 3" valves in a sbf head.
sounds like these 4v heads might move a bit more air than fully worked 2v heads.
AND; the 2v 4-second guys rebuild their motors and clutches every round. i doubt that is required at the 7-second level...

the numbers will come when someone gets serious about boost with these bad babies.

100 HP difference N/A!
nice!

they claim to be a true bolt-on with all the water ports/bolt holes in the stock location.

Ok, 2 valve small blocks without any power adders. 6.80's or so. There are no 4 valvers(NA) that even come close to that right?

The 4 valve will not move more air then a real good race 2 valve head. But, I don't think that the 4 valve head is a full tilt race head. At least nobody has used it yet that I know of.

I know of many parts that claim true bolt on and are a pain in the ass to put on. So, don't always believe what you read. Especially on the Internet and magazines
