I was just curious as to if anyone has had any experience or tried Powerheads? I am a little interested in them for only $675. I know what you all are probably thinking, save your money and buy a good set of iron or aluminum heads. I agree, but anything has got to be better than our GT-40s we currently run. With all the companys selling heads nowadays, it is really confusing as what to run, not to mention THEY ARE EXPENSIVE!! I just cant justify that kind of money to bracket race, well not right now. It would take two years to save that kind of jack. I am very sure they are worth the money, but it is still a hard pill to swallow. Any feedback is appreciated!!!

I'll do a little research Steve. One of our suppliers carries them.

the gt40-p heads are hard to beat for the money. $500 per set complete.

One of the guys in the Pantera club used their Aussie closed chamber
2V heads on a 351C build up. Powerheads purchase the heads in bulk
directly from Australia (probably through Mike Fielder) and can
therefore get the cores inexpensively. I think you only save $100
or so if you supply the cores (for an Aussie 2V port job). Since
they get the cores so cheap, they can price their finished product
accordingly.

Charlie is an American living in Spain and was having the work done
by a shop in France. He was looking to run the car at triple digit
speeds for extended periods on unresticted European highways. His
Pantera had a stock block that he wanted to retain (cast dished
pistons) so I suggested the following build:

Aussie 2V closed chamber heads
Weiand Xcelerator 2V intake
Holley 700 DP
Comp 282S solid lifter cam
Hedman Pantera headers (1 3/4" primaries, 29" long, GTS collector)
Roller rockers
Double roller timing chain
Moroso oil restrictors
10 quart Aviad road race oil pan

I don't think Charlie shopped around much but based upon the few
shops he called, he didn't think he could beat Powerheads price on
sourcing the heads and doing the machine work (valve job, mill and
drill for studs and guideplates). He opted for their port job with
4V sized valves. I sent the Weiand intake to Powerheads for Charlie
so they could port match to it. I also strongly suggested that he
run 2.1"/1.65" valves instead of the 4V's and told him to order a
complete Comp Cams kit though Alex so he'd be sure to get the right
springs. Powerheads talked him out of both suggestions, installing
their own springs and 4V valves. This came back to haunt Charlie.
On a long, high speed trip, Charlie experenced some valvetrain
problems (rockers backing off, bent pushrods and ultimately a bent
valve). The problem turned out to be the Powerheads springs. That
error caused him a lot of time, money, and grief. While it was
running, Charlie was very happy with the engine combo, though.

Another guy in the club used Powerheads, again because they could
source the Aussie heads so cheaply. This time it was for a Mangusta
with an overbuilt Boss 302. Steve wanted to tame it down some for
the streets but wanted to keep the Boss 302 look so he decided to
do a Street Boss conversion. I let him talk me out of my intake,
suggested a Comp 270H cam, and he ordered up a set of Powerheads
Aussie 2V heads. When he received them, he noticed they were two
different casting so he C'd the heads and sure enough they weren't
the same. Powerheads did make good though and exchange the head
for a matching casting.

FWIW,
Dan Jones

These are the 2V closed chamber Cleveland heads, no?

Why on earth would you replace wedge heads with these to save money? It'll nickle and dime you to death by the time you have the intake,valvetrain and fasteners these take to adapt. A set of aftermarket wedge heads are a better way to go. Save the C heads for C engines.

Who's changing heads? I was just relaying a couple of experiences with Powerheads the company. I wasn't suggesting he change heads just that he be careful dealing with them.

I am looking to change heads and was curious about the Powerheads. I run a 351W in an 84 Mustang with 11:1 compression and wondered how they would work on it. Any info on these or this company would be greatly appreciated.
