Guys I'm putting my lq9 back together and its going in a 2001 GMC and I was wandering what heads I should go with let me no what you thank and its getting a Torquer 2 cam as well thanks!!

 

Depends where you want your powerband

 

im fixing to do lq9 with ls3s. ls3s have lighter valves which are a big plus for revving and maintaining a light and stable valvetrain. can make more power with less cam and less money as opposed to expense of very good 243s and a fast 102. ive done my research and hope to complete in next 3 months hopefully. also in a 2001...low2001gmc

 

if your running a TORQUER 2 cam from TSP that cam is for cathedral port heads not rectangular so imo 243s L92s probably won't work so good with that cam but then again I'm not positive on that either.

 

I would not build an engine around the cam... I would plan out the engine then get the right cam for the end goals and the rest of the build.

 

I SOMEHOW MISSED THE TORQUER 2. WHILE SOME HAVE USED THE CAM WITH LS3/L92 HEADS AND IT WILL WORK, IT WONT BE OPTIMAL AND "PTV" CLEARANCE WITH STOCK PISTONS CAN BE ISSUE. SO I WOULD SAY THOSE ARE 2 GOOD REASONS I WOULDNT USE THAT CAM. THE HEADS WILL WORK FINE OTHERWISE. HOPE WE ARE ALL HELPING SOME.

 

This.

 

Well I have the cam all ready! I was running it in the stock lq9 but I figured I would put heads on it instead of the 317s I was mire it less looking for a little more power with what I have all ready

 

save up and get some advanced induction 243s, tea 243s or tsp prc ls6 2.5s. if on a real tight budget, milling your 317s some .030 to bring ccs down to about 65cc and raise compression to about 10:9 would help. just depends more on budget i guess. feel free to pm with any ?s. rob

 

like stated if your not looking at buying another cam just do a set of ported 243s I'm running a set of ADVANCED INDUCTION 226cc 243s on my LQ4 and so far they've been awesome
