2023-02-25 - Aftermarket Non OE Cylinder Head and Valve Train

Q:
If you take a cylinder head swap off the VPI list on a OHC engine you acquire the cams and valve train.
If an aftermarket head like Brodix trick flow was purchased on a V8 engine you can claim roller rockers and other valve train.

If an aftermarket casting for an over head cam engine in this case Honda is available are any cams and valve train included in the head swap?

A:
A billet head swap does not include valve train and it has to be added.
If swapping factory offerings the rockers and springs come with

I ran this through the TAC and although factory overhead cam head swap includes cam and valvetrain we cannot do the same for an aftermarket billet head. The cams have to match original to the engine for no additional point add.


I know this is not in the rules but it's kinda new stuff coming out. It is the feeling allowing this would lead to + $$$$$ and that is not the direction we want to go.
Sorry it took so long to get back with you but it takes time to go through the process.



Summary:
Cam in block engine:
Aftermarket cylinder head swap = No pushrods, rockers, Valvetrain components included
OE cylinder head swap from another vehicle on vpi list = OE pushrods, rockers, valvetrain from head being swapped included in head swap points

Overhead cam engine:
Aftermarket cylinder head swap = No cam(s), rockers, valvetrain components included
OE cylinder head swap from another vehicle on vpi list = OE cam(s), rockers, valvetrain from head being swapped included in head swap points
