Hello Gearheads and Happy Formula 1 Sunday Australia. Have you ever wondered what cylinder head prep work it takes to accept 1/2” ARP head studs, B16/GSR cylinder head? I just finished editing a 7-minute YouTube video showing what it takes to do the job right from start to finish. Cylinder head is going on a B-Series Billet Aluminum Block. There is a lot of good information regarding this procedure. Knowledge is power. Please like, share and subscribe. How can ALANIZ Racing Heads help you?

Hello Gearheads and Happy Sunday. A German Vintage cylinder head from the 60’s came in for some repair work. Water jackets were badly corroded. The cylinder head was ready for the scrap pile. These are very rare heads and no longer in production and what you can find for sale will give you a heart attack price wise. Here is how ALANIZ Racing Heads gave this cylinder head a second chance. Never a hack job. Quality work and craftsmanship. How can ALANIZ Racing Heads help you?

Hello Gearheads. HONDA parts on a Datsun head? A very rare and limited cylinder head came in to get worked on. This is the Datsunworks KN20 cylinder head used on Datsun 6-Cyl L-Series blocks. This is a well-designed casting based off the Honda K20 cylinder head. It uses all Honda valvetrain parts. Head also uses Honda K-series semi-finished camshaft lobes shapes ready for your specifications. Casting is A356 aluminum, is made in USA and the use of 3D printed sand moldings allows for an intricate design inside and out. I will be machining in virgin seat angles, setting valve heights and minor porting to compliment the valve job, ready to bolt on cylinder head. I will be aiming for good flow numbers in the .250”-.550” valve lift. I’m not looking for Drag Racing flow numbers in the .700 lift range. 4-Valve cylinder heads are my specialty and my 20 years of Flowbench testing and experimenting on Honda K- Series Heads will come in handy. Stay tuned for updates. Cylinder head design is by Datsunworks and thanks to Erick Aguilar from Erick’s Racing for choosing ALANIZ Racing Heads to take on this project. Credit where credit is due. Always. How can ALANIZ Racing Heads help you?

Hello Gearheads. HONDA VS. THE WORLD continues on this Formula 1 Sunday Brazil. Stock Honda S2000 vs. BMW CNC ported E30 race head used in BTCC (British Touring Car Championship 1986-1991 era 2Liters) See comments for porting/chamber/valve pictures. The E30 intake flow is identical to the stock S2000 head from .050” to .300” valve lift. The S2000 then comes to life at .300”-.500” valve lift. An S2000 will see about .485” valve lift, Japanese racing camshafts. FYI the stock S2000 has 36mm intake valves. The BMW E30 race head has 38.5mm intake valves and is CNC Ported. This is Flowbench testing I did 20 years ago. When it comes to porting/modifying 4 valve per cylinder heads, hundreds of hours on the Flowbench equals knowledge and knowledge is power.

Hello Gearheads. HONDA VS. THE WORLD continues this Monday afternoon. The Honda S2K F20C1 cylinder head is the best flowing 4-cylinder head Honda makes in 100% stock trim from the factory. So how does it compare to a Ford GT500 fully CNC ported Cylinder head? FYI…. Honda has 36mm intake valves vs. Ford 37mm intake valves and very steep intake port angle. See Photo in comment section. For 37mm intake valve and very high intake port design I expected better results. In all honesty am I being bias toward Honda? No. The truth is Honda just makes awesome cylinder heads.

Hello Gearheads. Some more Sunday engine talk. When it comes to a Performance valve job, what seat angles or shapes are best for your application? Pictured below are two common valve jobs used. The 3 angle valve job and radius valve job. I always begin by asking the customer what is your application? Naturally Aspirated, Forced Induction, max valve lift, Street engine or Race engine? Countless hours of Flowbench Testing various valve seat shapes for various cylinder heads, has helped me to know what works for your applications. This is just one of the ingredients to a well prepped cylinder head, engine combination. More engine Tech coming soon. How can ALANIZ Racing Heads help you?

Hello Gearheads. Let’s give you something to talk about this Sunday afternoon. HONDA VS. THE WORLD on my Superflow Flowbench. Honda B16 vs. Nissan RB26. How do they compare in stock trim? Over 25 years of Flowbench testing all kinds of import cylinder heads. Flowbench Testing and Testing and more testing has helped broaden my knowledge of how air flows through a cylinder head, what works, what doesn’t and how it equates to real Horsepower numbers. HONDA, TOYOTA, NISSAN, DATSUN, MITSUBISHI, MAZDA, ALFA-ROMEO, BMW and more. Lots of Flow testing data coming to give you something to talk about. Knowledge is Power. In the Honda Racing game since 1993. How Can ALANIZ Racing Heads help you?

Hello Gearheads. Sunday school is in session. K20 PRB vs. NSX C32 cylinder heads on my Superflow Flowbench. Which one flows more or better yet, which one has a better flow curve for your camshaft lift? Just letting you know the Acura NSX has a max lift of .390” with lash set on the big lobe. Making the NSX cylinder head breath well in the .500"-.700" valve lift makes no sense. Flow numbers may seem awesome to brag about at higher valve lifts but the NSX cylinder head will never operate in that valve lift range. Having a Flowbench helps me make improvements on targeted valve lift areas. Knowledge is Power. More Flowbench Test Data coming. How can ALANIZ Racing Heads help you?

Hello Gearheads. Work from 3/12/19. A badly damaged cylinder head came through for a repair. One completely blown out chamber with all the others in bad shape from shrapnel. These kind of repairs are time consuming. No clean, shiny and grease free aluminum to work or weld here. After the repair there were some minor blemishes and a bit of porosity but overall I was happy with the repair, Pentroof chamber reshape and porting upgrades. How can ALANIZ Racing Heads help you?
