Whether you are looking to do a mild cylinder head rebuild due to a head gasket failiure, or worn valve guides, or you are looking to maximize your cylinder head for every bit of horsepower we have you covered!
Please check the drop down menu carefully and chose which options you would like to add.
Our Standard cylinder head package Includes a full rebuild of the cylinder head using GSC components.
For an additonal $500.00 your cylinder head intake and exhaust ports will be hand ported and polished to our Race Head specifications, We also perform our combustion chamber reworking and polishing which will reduce chances of hot spots and detonation since all the stress risers will be removed in this process!
For an additional $300.00 Stainless Steel O-Rings can be added to help seal the combustion chamber under high boost/ high RPM operation.
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.
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.
