Then I will DEFFINATLY be in if its 15hp for N/A cars, we will see.

Im not yet familiar with the Z heads/Vvel yet but if you're going to do cams you might as well do head work. Working the flow of the heads is the secret to hp on na engines. Im surprised this isnt discussed more often in this forum. I know people have mentioned that the vvel tuning hasnt been cracked yet. I do not understand why this isnt a priority for the shops with the resources. Ive head work done on most of my cars including those with forced induction and its a night and day difference. Some Ive sourced out and some work I did myself.

Did you do headwork on the 370 though? by all accounts, the 350 and 370 heads are already there.

How do you know they're already there? Did you do any bench flow comparisons? Ive never seen any flow charts for the Z heads. All I see is a lot of he said/she said. Its something to look into. Unless a shop has done these test I dont just take anyones word for it.

"...by all accounts"

I'm pretty certain i've seen Motordyne flow testing the heads and finding nothing.

Did Motordyne do a before and after test ?? or is this a visual verification ??

It was flowbenched.

:iagree:

Can you do even do head work on the VVEL valves without screwing up the calibration? I haven't heard of anyone messing with it yet...

I was talking to the owner at track forged in Oregon about my winter build (mentioned the JUN exhaust cams to him) and he mentioned porting the heads and that they make a huge difference which I understand. He didn't mention anything about the VVEL having an issue but we both were "brainstorming" about the idea of how the VVEL motors would react to it. Hopefully someone does it before me so if it goes bad I can back out of the idea but if they don't then I will be the first :/ oh well, someone has to find out eventually.

You got an install date yet?
