who makes the best port polished, extrude horned big valve head for the MK3 OBD2 VR6.??preferably somewhere on the east coast. and what kind of numbers should i expect for air velocity and air volume when its hooked up to the bench flow? would it be a good idea to have the valves blue printed and balanced?? and lastly, what other things need to be changed when removing the head??. hydrolic lifters?? i want to match it up with 268 and intake manifold, what are possible power gains?. thanks

From what I have heard CCH makes the best BVH's. You might want to contact JimChu(vortex screen name) he usually has those types of things hanging around. Good Luck. http://****************.com/smile/emthup.gif

I would look into Trac Racing and Bill Schimmel(sp?) I have heard great things about both of their heads and Stephane and Bill are both very knowledgeable when it comes to the tempermental heads of our VR6's. You can't beat the experience gained from racing on a track.

Well, although Trac and Schimmel offer some nice heads, they're not ones with enlarged valves. Both are just P&P'd and flowed.
CCH is the only shop that makes true big valve heads with the Schrick valves. V-dubz.com sells them now that Velocity is gone.

You'll get almost 30 wheel hp at 6600 rpm.
Here's another one with a VGi - It's a little lacking up top with it.

If you have a strong motor to start, your percentage of increase should be similar.

I have the CCH/big valve haed on my vr6/2.8 Best dyno pull 4th. gear 193whp.
This is on pump gas (93) with a can of liquid go mixed in.
The bottem end is stock ,with flywheel ~11lbs ,UR pulleys, vg ,giac chip,268cams, some mild port work to top of vg and lower runners.
Best dyno before head 169whp .
You will lose a little bottom end 3500rpm and lower,but above 5000rpm it'll scream.
P.S. put a shift light in! For 1st/2nd gear, or you'll be bouncing off the rev limiter, the tach will be a little slow .

Re: Best Big Valve Head for MK3 VR6(obd2)?? who makes it (Needs More Salt)

The real gains of a BVH come in with a larger dispacment engine, a larger engine needs more air of which the bigger valves can provide.
We really need to get a GB going on these CCH heads they are REALLY expensive!

so it's really hard to break the 200whp with a NA 2.8l VR6. i guess you would have to increase the displacement.
