High Velocity Ports (HVP) Spin Dropped Heads
This picture illustrates the work done to all stock Twin Cam heads used in our kits, or as done to your own heads when sent in for work. We have removed the valves to show the workmanship
We also ship the appropriate thickness head gaskets out with all jobs to ensure proper piston to head clearance.
- finished heads will have a combustion chamber volumes calculated and machined to yield the desired compression ratios - we can also adjust the cc volume on special order heads to accommodate different pistons - can be setup for use on 88", 95",103" or larger engines with varied compression ratios - for use on carburated or fuel injected models - heads are fully ported, decked, and have a fully radiused valve job - they contain new valves (1.900" & 1.625"), guides (manganese bronze), springs (titanium top retainers), and seals (Viton)
