Hey buddy!
That'd be awesome,and eventually I am going to run one that or a D15Z1.
As of now it has the D15B6 8-valve roller rocker head on it,and it runs suprisingly well.Especially considering the fact I'm running 16v pistons with a 8v head.
I'm kind of torn in the middle honestly..The Z1 is a incredible motor and the 3 stage is the best of both worlds..I actually ordered a head off of eBay and UPS damaged it in shipment by the time I got it it had bent valves and a broken solenoid.So I'm keeping my eyes open for another one
