A little background of myself, I have been a member here on LS1Tech for 4 years. My screen name is LongIsland63SS409 https://ls1tech.com/forums/member.php?u=171521
I have a 100% trader rating purchasing/selling from LS1Tech.
Last year I was putting together a 6.0 LY6 for a street/strip 98 Camaro I am building. I wanted to keep the VVT cam setup and decided to go with a Texas Speed VVT-3 cam.
During the build I designed and received a patent pending for the VVT UNLOCKER.
MS RACING COMPONENTS, LLC was formed and signed up as a sponsor. It was always a lifetime goal of mine to create a company thus MS RACING COMPONENTS was created.
Working on another video that shows the VVT UNLOCKER checking piston to valve clearances.
Please post any questions about the VVT UNLOCKER as I can address them on this forum.

In your build with the Texas Speed VVT-3 cam what are the specs on the cam and what ICL was the cam installed on? How much exhaust valve to piston clearance did you have with the cam at full retard? What was the amount of full retard in deg? Did you use a phase limiter? Thanks
Yes, using the Comp Cams Limiter that limits the total cam retard to 22 degrees. Cam phaser is locked at 7 degrees advanced without oil pressure so the full cam retard past TDC is 15 degrees.
I am going to retake the PTV clearance measurements again for a new video I am going to make.
The stock LY6 piston I am using has deep exhaust valve reliefs but the PTV is significantly reduced when the cam is fully retarded.

Texas Speed VVT-3 Cam is 231/239 @ .050, .617/Intake .623/Exhaust, ICL 110, 113 LSA.

Okay so If the the cam was installed at 110° ICL at full retard the cam would be at 132° ICL and the exhaust would be at 94° ECL. What do you mean by full cam retard past TDC is 15 degrees? So when do you plan on checking the exhaust valve to piston clearance and making your new video?

The cam phaser with the Comp limiter installed has a range of 22 degrees. It is locked in the park position at 7 degrees advanced and can rotate counter clockwise (retard) 15 degrees for a total of 22 degrees.
Looking to have the video done within 1-2 weeks.
Impressive 10.93 ET with your car.
What cam are you using?
Did you keep the VVT?

Yes I keep the VVT and the cam in it is my design! 
The VVT gear has 7° more advance than the standard gear so doing a cam for VVT you have to take that into account. The VVT gear can only retard the cam the 22° with the phase limiter. So like I said if you degree the cam in at 110° ICL at full retard position the ICL will be 132°. Thread Starter

Worst case is .060 on the intake and .085 on the exhaust.
The VVT UNLOCKER made the task of checking the clearances easy.

Awesome on using a custom VVT cam that you spec'd!

Which are you going to flycut intake or exhaust? Was the .085 on the exhaust at the full retard?

The exhaust piston to valve measurement was with the cam at full retard.
The cam phaser has the Comp limiter kit installed also.

I see sense you are going to mill the heads that you need to flycut the intake side but why flycut the exhaust. What would you ever need to run the engine with the cam 22° retarded for? Just asking.
