I'm thinking this head, adjustable cam gears, reving to 8500rpms, stock pulley (because it'll hit the max peak rpms at 8500 engine rpms.), ported intake manifold, meth injection, dual pass, killer chiller, SICK!

the head was the same price as listed in the special preice they had listed. It is true the head did make almost as much as the ts did this shows you how much power is hidden in the head now with the ts we will see how much the head helps the ts.

It was $2000 I drove down to my aunts house and picked it up. WELL worth it.

yea, I'm thinking about it, not sure if I want to break the motor apart before the car is paid off, but that is some serious hidden power potential. Thank you for being a pioneer and showing us what the car can do!

So this is all working on the assumption that the stock head flows significantly less than what the cams allow? Sure would be a decent oversight by quite a few engineers who designed it. Must be a heck of a valve job.
If only someone had the flow test results of the stock head with stock cams and higher lift cams.
