We always start with a new cylinder head casting. Since the ‘newest’ used head is at the very least 17 years old (and up to 25 years old!!), we prefer to start with a new casting. Most of the used core cylinder heads we see have been machined at LEAST once in their lifetime. Cam journal wear, cam bearing line bore, cracks, warpage and coolant passage electrolysis are ALWAYS an issue. Rather than “band-aid” a head back together and sacrifice quality and durability, we start fresh.

Having inspected all of the new cylinder head castings available on the market, we have found most to be of inferior quality (poor castings, porous material, improperly machined cam journals etc.). We have chosen a manufacturer that uses an improved material that is less prone to cracking and electrolysis (corrosion of the cooling system passages).

 

We build this cylinder head to get the most usable power from your Toyota when using your stock fuel system (EFI or carb.) The cam profile, oversize stainless steel valve design, valve springs, port machining and valve seat profile cutting have all been designed to work together for the best performance. Idle remains smooth and power is available from 1250rpm to 5000rpm.

 

 

 

 

 

 

We have cutting bits custom made to our profiles by Newen for our Serdi 3.0 machine. The intakes are cut to a 4 angle (and a back cut to the valves) and exhaust seats are fully radiused. Other shops call this a “full race valve job”, it’s standard on EVERY cylinder head we sell.

(picture shown is before port work)

The head is then taken to our downdraft booth for port work. Both intake and exhaust pockets at the valve area are hand machined, radiused and polished for improved flow.

We back cut the intake and exhaust Ferrea 1mm oversize stainless valves and set the installed height. We install Viton valve stem seals and our 70lb. performance valve springs.

We use Joe Gibbs Racing high zinc assembly lube when we install our custom ground OEM camshaft.

NEW cylinder head bolt kit

We always recommend new head bolts when installing a new head or when the engine is rebuilt. Your head bolts are at the least 14 years old and have been through countless heat cycles. Recommended to hold proper torque.

When installing a new cylinder head, we recommend:

YES, we’ve seen them. The “NEW COMPLETE” cylinder heads that other web retailers, E-auctions sites, rebuilders, and remanufacturers sell you and we have found the quality to be laughable at best. The valves and springs are of inferior quality. The ‘valve job’ to match the valves to the seats and installed stem height is not even performed. The most common problem we see is the exhaust valve seats are such low quality, the exhaust valves start “sinking” into the seats. We don’t even see this issue on original Toyota engines until about 250,00 miles. We’ve seen this issue on aftermarket heads within 5,000 miles. Low quality parts and poor cylinder head castings are imported, stacked on a shelf and then everything is assembled without regard to anything but speed to get it out the door and taking your hard earned money. The new camshafts they install are a VERY bad quality that are not built to last. Their ‘complete assembled head’ sounds good on paper, but we’ve inspected them and the quality is severely lacking. Not worth your hard earned money and your time to install it (and you’ll do it a few times more). It may take a little more time to build a cylinder head for you, but it is done the RIGHT way. No corners are cut, everything is triple checked and we use nothing but the best parts and machining procedures. Check out the build procedure box below for a complete breakdown of our build process, and please feel free to call or email with any questions you might have.

This head features:

add $110.00 for Titanium valve spring retainers (lower reciprocating weight, faster revving)

 

Even though we start with a NEW cylinder head casting, it is still not good enough. The first step is to remove all of the exhaust valve seats and replace them with HARDER powdered metal seats for longevity. Both the intake (a 5 angle cut) and exhaust valve seats (fully radiused) are cut to our custom profile (using our SERDI 3.0 seat machine) to match the new intake and exhaust valves we install. Installed valve stem height is inspected and adjusted as necessary. All valve springs are NEW and are installed into the cylinder head.

The cylinder head is then surfaced on our STORM/VULCAN surfacer (with a custom CBN head) and surfaced to the proper RA finish.

A OEM reground camshaft is installed (never a “new” counterfeit Chinese casting).

 

 

 

Included in this cylinder head:

We can also improve the performance and fuel economy of our stock cylinder head. We’ll hand machine to blend the intake and exhaust ports in the head to match the valve seats for improved flow.

$125.00 additional

FULL RACE cylinder heads with bigger valves (1.5MM), bronze valve guides, dual valve springs and extreme port work are available. Pricing depends on the cam you choose, valve size, amount of port work and your fuel / exhaust system.

Recommended only for racing / off-road applications. Call us with your needs and we can quote a cylinder head/cam combo for your class!

Due to the countless number of heat cycles yours have been through, it makes the studs incredibly brittle. The last thing you need when installing a new engine or head is to break a stud during install.

Our UPDATED kit includes all 8 OES studs and 8 self locking nuts.

ALWAYS RECOMMENDED
