Torquer cam coming, which heads or stay with LPE LS1 ported Well, my mods are listed below. Right now I'm running the Lingenfelter top end kit with their GT2-3 cam. I'd like to step up to something a bit more agressive and I like what I see in the torquer V2 cam. Will their heads make for a good combo or do I need to go with a different set? There are a TON of head options and I don't really know much about them.

I'll probably be looking to sell it. It's a fairly mild cam for NA, but people say this thing really wakes up with some FI. It is putting down some pretty good power though, and has pretty good torque down low. Fun for the street

were your ported heads milled at all? TSP said they ran the torquer on heads milled .015, but I was tight. Typical larger valves wont stick more than .005 further down the bore, so as long as youre not milled more than a few thou, you should be okay. I would double check with TSP or measure yourself just to be certain.

I'm not sure what the mill specs were. it's their standard top end kit, so i'll have to ask and find out. i was told by a shop that did some work on my car that the heads were hardly touced.

Running 2.050 valves, would have a radius .025 larger than stock. At 15* this would put the valve edge .0065 closer to the piston. (thats 6-1/2 thou.) That still leaves .0085 for the mill. Of course this does not account for larger than stock valve margins.

some head porters hang the valves lower or higher on the seat after the valve job. just using that method could be dangerous.
i know my 2.040 valves have about .030" less valve drop than stock, and that is not all from the bigger valves.

I shot an email over to LPE to try to get some specs on the heads. Hopefully they'll work for me. Even if they do work, is there a better choice for heads with this cam? Will it make that much of a difference to make it worth spending the dough and performing the switch?
