I'm getting ready to put heads on my car and need to know what kind of PTV clearance I need for my set up. My Setup is a Tourqer 2 with a set of LS6 heads decked .030, and I'm running factory head gaskets. Also is the 7.4 push rods I have going to work also?

 

Generally accepted rule of thumb:
At least
0.080" intake side
0.100" exhaust side

 

More info on heads needed. .030= 5cc, then better check you PTV
Also what is the LSA and advance (ICL) in this TV2?

 

The heads are set of Livernois Stage one LS6 heads. The LSA is 112, and Im not totally sure on what ICL is, but I do know that the cam was installed straight up dot to dot no advance.

 

it will be close.I have ls6 heads milled .018",cometic .045 gaskets and a 228/230 on xe lobes and a 112 lsa and i have about .085 intake and .135 exhaust.just check it

 

Yea I plan on checking it no matter what, but I was just curious what everybody's thoughts where

 

Bigger valves on the heads?

 

there stock valves

 

here is what they are

CNC Ported Stage 1 GM LS2/LS6 Cylinder Heads


New GM LS2/LS6 243 casting
5 axis CNC machined
Fully assembled
220cc Intake Runner
Intake Flow Rate 305 CFM
Exhaust Flow Rate 235 CFM
New 2.000 intake valves / 1.550 exhaust valves
GM Valve Seals, Retainers, and Locks

 

It "should" fit with stock gasket. But better measure.

 

Thanks man thats what I was wanting to hear, but I will still check no matter what. Greatly appreciated
