LQ4 Potential PTV Clearance Issues Hey Guys,
I bought a turbo cam a while back and was thinking I might have potential PTV clearance issues. Here is the setup.
2004 LQ4, slight dish
LSA heads, unmilled
LS9 head gaskets
Lift:
0.610" intake
0.593 exhaust
LSA 115
Cam advance is 5 degrees
Duration
Intake: 235
Exhaust: 242
Thoughts?

If your asking about PTV, you’ll have to check it. No way without the correct software, that anyone could guess it for you. And even if I had the software, I wouldn’t trust it if it were close. When in doubt, check the PTV. Takes all of 30 minutes, if the heads are off.
