Default LQ4/L92 Carb Cam Question

So, I have been looking through the carb database and not really seeing what I am looking for. I am wanting a cam for my spare motor. (regular motor will be a same setup but efi and its already built).

Some specs on the motor are:
86 lx notch foxbody weighing in at 2700 without me
3800 stall
26 or 28" tire.. havent decided yet
th350
4.10 gears
l92 heads
lq4 block with arp rod bolts
edelbrock performer 750
stock headgaskets.
vic jr intake
90% track/10% street

Looking for a cam that I can put in without having to flycut and use the stock headgaskets or slightly smaller if that would be better.

Appreciate the input and thanks again!!

Kinda thinking about the Comp Cams 277LR HR13 but found an article stating that it would be a very close fit with the PTV. Can anyone verify?

the cam in my 5.3 has .617 on the exh and .610 on the intake, I shaved the heads down .030 and still have plenty ptv clearance even using new tfs 7.4 pushrods and a head gasket compressed to .045". Idk if it helps but if you havn't touched the deck height, or heads I would think you'd be alright, but don't hold me on that, I could vary well be wrong...

I sent you a pm, but I`ll add this here, if your car is 90% track, I would go 1 step bigger than the cam you listed, and mill heads for compression, and flycut as needed.
