Whether you are looking to do a mild cylinder head rebuild due to a head gasket failure, or worn valve guides, or you are looking to maximize your cylinder head for every bit of horsepower we have you covered!
Our stage 3 Cylinder head is for anyone looking to absolutely maximize their engines power output with plans of making over 800 wheel horsepower. The stage 3 cylinder head Is CNC ported on the intake and exhaust ports, hand blended after the CNC process, the chambers are also CNC ported to remove any sharp edges that can cause fuel instability and detonation. The stage 3 cylinder head comes loaded with all the components that our stage 2 cylinder head has, with the addition of +1mm valves to take advantage of the bigger ports, and the O-ring’s and valve springs are already included in the package.
Please note, the 4B11 Cylinder head package costs $200.00 Extra due to the solid lifters/buckets that have to be adjusted to each cam lobe, the extra labor required to properly do the job is the reason for this price increase.
Valve springs can also be upgraded/added at an additional cost, We only use the following valve springs in our cylinder head builds.
· Kiggly Race Only Valve springs + Retainers + $400.00
We recommend the 5041 beehive valvesprings for applications that will not see over 40 psi of boost, the 5041 beehives provide very good seat pressure and are gentle on the valve train.
The Kiggly Race Only valve spring kit is for 45+ Psi of boost applications and offers a great amout of seat pressure that can be hard on the valve train in the long run, so it is only recommended if you really need it in your application!
Customer Supplied cylinder head core required, If you do not have a cylinder head to provide as a core, a new core can be provided to you at an additional cost.
