I will be picking up a steel head from APT tomorrow. It is costing me
900 bucks, but 100 of that is for the core that David sold me. The package
includes Rimflo valves, double springs, keepers, seals etc. The valves and
seats were cut with 3 faces. Phosphor bronze valve guides reamed to
critical tolerances with top hat style seals on the intake and
standard seals on the exhaust. The combustion chambers were ground and
polished to produce a 9:1 CR. The block was decked so the pistons were
within 5 thou of the top of the block at TDC. David machined the head to
produce the correct CR. While he was working on it, he says he got
confused about what I had asked for and went ahead and ground the ports for
more
air flow. He says I am getting a $1500 head for $900! WOO HOO!
Shooting for 90 horses! That ought to be a kick in the butt of the
Bugeye!

Having had both, my ass in the seat tells me that $ for $ the aluminum
head
out performs the steel version.
That is, for the price of an aluminum head the large percentage of us
cannot
build a steel head that will perform better.
David Anton might but he would have to throw in his work for free to
keep
the cost down if he were to sell it.
Most of us could not do enough of the work ourself or the quality of
the
work necessary to make it happen.
The aluminum head performs right out of the box.
My guess is that if you were to buy the steel head on the open market
you
will have to pay $1300 to get one that will out perform the aluminum
head.
BTW Cap'n Bob my aluminum (Pierce) head uses the same plug as the
steel
head.

Hey Cap'n,
I don't know where you get your numbers from to make this claim,
but
I have recently heard from an extremely knowledgeable and well
known
source that the aluminum head does NOT flow as good as a stock
cast
iron head and that if the extra money spent on the aluminum head
invested in even mild porting of a stock head with Rimflow
valves
would perform much better. I only recently heard this and was
surprised myself, but the credibility of this individual I think
is
without question. If you have some factual data to back up your
claim, I'd like to hear about it.

Hey, Bob....consider.....
That aluminum head is not only
lighter, it also flows around 30%
better than stock, runs cooler, uses 12mm
plugs due to a "centered" plug in the
combustion chamber (more even burn
across the piston) and comes with
hardened seats.
