hey whats up guys i have a h23a vtec that came with dual valve springs stock. My question is,
does anyone know what the specs are on this head?
do any other H series heads come with dual springs or do they all?
can i get some aftermarket cams with these valve springs?

so far i have purchased:
Skunk2 Valves High Comp.
Skunk2 Pro Series Stage 2 Cams
Skunk2 Pro Series Cam Gears
Supertech Valve Guides

 

If you are running pro2s then dont even worry about the strength of the stock springs- just buy the correct aftermarket ones. The stock springs will not support the pro2.

 

Get the aftermarket springs. All H-series VTEC heads came with dual valvesprings from the factory.
