I have sets of brand new CNC'ed LT1 heads boxed up and ready to ship. They're flowing an astounding 352CFM over 297CFM stock! Note the significant gains above .550 as the stock head flow starts to decrease.

$1899 shipped with core exchange

Boosted setup has compression lowered - 66 cc chambers
N/A setups have compression raised to 11.7:1

Included:
Includes fully CNC ported intake and exhaust ports, custom valve jobs, bowl blending, blending of core shifted intake and exhaust ports, milling for desired compression ratio, build sheet, final wash and assembled. (315cc/116cc)
Double springs, titanium retainers, locks, seals
Rockers with trunion upgrade

How much without core?

What's stock compression on c7?

While I'm asking questions, are any of your cams designed for blowers, specificly centris?

I'm thinking my next mod will be heads and cams :-)

these heads look fantastic! surprised the stock ports flowed so poorly

I would have thought they were 330 out of the box

I'll have to check core charge to replace Greg but probably int he 8-900 range with valves and rockers etc.

OEM is 11.5:1 CR and we can go down for boost.

Yes I have blower cams so you can overdrive fuel pump and make more power with more boost and lower CR. E85 and my flex fuel sensor will help you with the tuning window too at approx 105 octane but the Z06 mechanical pump will be needed for that.

Flow benches are like dynos and vary as I've seen other places post them at 330 CFM if I recall. The important part is the gain and these are at 60+ CFM! My big valve set are +100 CFM!

You have to pull the heads to replace the cam correct? I would assume the Z06 fuel pump is easy to replace since it's mechanical?

Still have one NA set ready to ship!

Just got another set of N/A heads ready to go!
