Oversized valves on a d16z6, how big can i go >?
how big should i go for a 500whp turbo d16z6, it's almost done being ported/benched, gonna run the stock cam, and aftermarket valvetrain,
i was thinking .5 exhaust, 1mm intake, can i go that big ?
also, does anyone know the stock flow of a z6 head ?, and an aftermarket ported head, i sent out a couple emails but people are really reluctant to release flowbench numbers on genericly mass ported heads(i wonder why)

B series have issues with valve to valve contact if you are using big cams and oversize valves, not sure about D series though. I have a B with +1mm valves on intake and exhaust along with skunk2stage2 cams and no issues.

Re: (Kelly.)
stock cam is fine for a turbo app, it's a lot harder to properly tune a aftermarket cam to the engine than just doing a well built solid setup
stock valves i won't trust past 500whp
stock valves won't flow as much cfm as a larger valve that goes well with a ported header,
increased volume, increased flow,
BUMP.. anyone.. =\
