Hey guys I just got a 01 Z06 with a LG G5X3 cam. A buddy of mine has a set of P&P TSP 5.3 liter heads that flow 315@.600 lift. They have been milled to a 59cc chamber. Can I run these heads on my motor without flycutting the pistons? Will the gains be noticable? Should I go ahead and switch over to a P&P Fast 92/92?

 

The p/v will be to close with a milled head on that camshaft. Your best bet would probably be to send over your stock castings & we can cnc port them & reassemble. We charge $650 to cnc port, valve job, mill & reassemble your cylinder heads.

 

Id send the ls6 heads to texas speed like jason said and swithc to a fast 92/92

 

What kind of power gains would I see from the cnc port and switching to a Fast 92/92 setup? Would that help at all with the cam surge that I have?

 

I think the cam surge is more in the tuning but i could be wrong

 

Yeah I was thinking of having Vengence re-tune the car and see if that helps.

 

Sounds like you gota plan im going to be taking my car to vengeance when i get my cam swaped in

 

I amy go ahead and have the heads worked and do the 92/92 setup before I retune.

 

Thatd be better, so you dont have to get it tuned again after

 

This may be a stupid question but are LS6 heads aka 243's?

 

Yes ls6 heads are 243s

 

I got a buddy who is going to try and work on the tune tomorrow and help the cam surge issue. Is there any aftermarket heads I could use with this cam and not have to fly cut the pistons? I would really like to get to 500rwhp N/A. There is a shop in my area I found out about tonight that can flycut the pistons but I rather not do that.

 

Well looking at LGs site they sell afr heads so im guessing they suggest running those with the cam. They have a dyno sheet on there of a 04 Z06 with afr 205 heads and g5x3 cam and it made 486rwhp. I personally would run trickflow 215 heads

 

500rwhp is possible, but it's pretty tough. With the PRC 215 head, ported fast intake, larger tb, electric wp, etc you have a chance. We typically see 40rwhp from bolting the PRC 215 on the LS6 engine!!

 

Can I run those heads with my current cam? I want 500 +/- you know? It don't got to be 500 on the nose but close would be nice. Send me a PM on how much to buy the heads and the Fast ported 92/92 setup.

 

Dam this sounds like one hell of a cam and heads combo!!!
