Joe Alaniz is no longer in business. Do not send him money or parts. He will keep and not return your parts and money.


This head is freshly ported and polished by Joe Alaniz. This is the unobtanium and I have it in my possession. No wait, no worries.

The porting is a clone to the head I am running. Supertech oversized stainless steel valves (1.0mm exhaust, 0.5mm intake) with Eibach dual springs and custom titanium retainers. The head has new valve guides and seats. The head combustion chamber volume is close to stock.

Flow bench testing says this is an excellent head.

This head on a boosted S2000 will add about 12 to 15 percent more power. Just what you need for that added little bit. This is the best power adder (IMHO) hands down. Several of the local 400 rwhp guys have Alaniz heads on their cars.


$3000 outright. Shipping and insurance included to the lower 48. Paypal add $95.

I will credit back $600 for your good head in exchange.

This is a very rare item and should sell quickly so if you want it act now.

Just to add for the seller. The Alaniz head on a bone stock F20C, as in stock cams and pistons, made my friends landspeed car that has run 201mph make 240whp.

so, if this head were to be put on a 'bone stock' ap1, it would add power also? no loss in power on low rpms?

Let me clarify bone stock, the motor was open header with alaniz port matched IM with no filter and AEM EMS. The block itself was stock in aspect of cams and pistons.

This head is for boosted applications. I saw 4 rwhp running one na.

for this... I personally have this exact head and I must say the work is amazing! Whos next to join the Alaniz head club?

^ I agree, bump for a great seller!

DAMNNNN I wish i had the money sooo badd. bump for seller and a excellent head!

any issues with running this head and a 3mm inlinepro headgasket??

No problems with running thicker head gaskets. The chambers are 54.2 cc

for a good seller

wow great price!! wish i was in the market to build my motor right now

Better check the valve radius on the piston. The Head Diameter for 1+mm is 32.mm for the exhaust valves. I had my first head done from Alaniz with 1mm oversize on the exhaust. After talking with JE and Wiseco both said there would be clearance issues. After inspecting that head is had a full row of bent exhaust valves. I was sold a head for NA and it ended up being a FI from Alaniz. Hopefully its one of his good ones. None the less good power adder for FI

Good to know.

These are extremely hard to get and this one is available. Who wants to add 50 horsepower or so?

This puppy has papers.

And, they should have your name on them.

what are the flow bench results from YOUR head?

yup, he just jams it in there.

The exhaust flow was increased over 30 cubic feet a minute.

Remains available.

Who doesnt love head?

Bump for a nice head that I would love to have....
