Stock LQ4+Torquer V3 cam??? Hi, I am new to the forum and can't seem to find a clear answer to my question in any past threads. I have a 2000 LQ4 short block w/unknown year alluminum 317 factory heads. Can I install the Torquer V3 cam without any valve clearance issues? The cam specs are 231/234 643/598. I am also using the th350 tranny with a 2200 stall converter. I also plan on using the PRC .650 double valve spring kit. Thank you for reading this and I appreciate any answers or advice. 
No they won't....well they might to the best of their knowledge. But they don't know your engine.
Nothing says the heads haven't been milled, deck milled...etc.
Only "hands down" answer is to check yourself...period.

This is absolutely the only correct answer.
That cam isnt a good choice, looks as if it has an LSK intake lobe which will give you issues. There are many newer, better, lobe designs avaliable. It doesnt cost anymore for a custom cam.
I also think the cam is too big for your combination.

You'll also either need alot more than a 2200rpm converter, at least 3200rpm but 3600 would be better. Also big cams and 9.4:1 compression don't exactly go together very good unless you don't mind lousy low end torque.
1.800" (installed height) - 1.080" (coil bind) = .720" (spring opperating range)
.720" - .643" (cam lift) = .077" (overall tolerance)
I guess they would work. Lol. My bad. But damn that is still a lot of lift.
