LS/Vtec Build
How To Measure Piston Ring Gap
1. Spray WD40 on the cylinders
2. Fit the piston ring into the cylinder
3. Push it down about 2 inches using an upside down piston
4. Use feeler gauges to measure the gap between the piston ring
5. Push the piston rings down about 5 inches and measure again
6. Repeat for all piston rings and cylinders
Clearances
Top ring - .20mm - .35mm (.008" - .014")
2nd ring - .40mm - .55mm (.016" - .022")
Oil ring - .20mm - .50mm (.008" - .020")
First I took the piston rings off an LS piston I had laying around I didn't use the P30's because the dome on them kept pushing the rings lop sidded

Pushing one down

Rings Pushed into cylinder

Measuring Gap(I love having small hands

ull be happy with it ... my lsvtec treated me nicely..even though i only put 7k on it..but every race i won with the exception of the rx7 with the ls1 that ran 11.77 on street tires..forgot the guys name but he pulled 3 cars from like 55-85/90
Thanks for the link, but the Pro1 info was just the usual "jawing" about cams, with no examples of an actual build.
My point to you about cams, is the process done thoughtfully involves choosing a cam and then building a motor to support it. Few would agree that garden variety, OEM parts LS/VTEC is such a build.
As you said, you have your heart set on the cams, but cams are best selected via the head, not the heart. I would like to see your first build succeed, but the little devil on my shoulder also would like you to be my Pro1/P30 test monkey. I already have another test monkey who munched a head with Pro2 cams advanced just 3 degrees.
Just be careful. Guys with a lot of building experience are dealing with the challenge of the pro series cams, namely dealling with cam tuning, clearance and idle issues. It does not appear to be a beginner builder's cam.

That's a pile of links that don't tell you anything about what you are trying to do.
Here's the reality, knowing its a big cam, your tuner is going to ask you how much valve clearance you have so he can determine how much he can tune the cams. Are you going to tell him you saw some guys on Honda-Tech who said they were great cams?
He's going to shoot you the "WTF" look and again ask you, as the guy who assembled the motor, exactly what your setup allows him in the way of cam tuning latitude. If you can't tell him, and if he agrees to proceed, it would likely be with the understanding that he may find out exactly how much latitude he has when your engine grenades.
You can't answer a serious question posed by your tuner by giving him links to a bunch of posts where the only thing certain is that forum users there know how to make thumbs up and thumbs down avatars?
I will personally pack my tools and help you degree your cams and clay your engine, if you like. Just message me. I am very curious and the information will be valuable to me for future builds. I cannot, will not install a cam with extreme lift and duration based on incomplete or completely uninformed information. Neither should you. It's not professional. It's not smart.
