Hey guys,

Just got this head ported and will be going back on my customer's car tomorrow. Dynosheet will be coming soon. For your information, this head was tested and flow benched 30 cfm more for each port.

Thought you guys might like some pictures:

The complete head job with oversize valve is around $3000 with parts and labor. You will be able to rev high and flow alot more air with this package.

Don't quote me but I believe they were flowed from .050 to .700 lift, I will try and confirm this on Monday though.

Not from us there isn't, every car we have done to date has undertaken a ton of other mods at the same time making the dyno data useless.
