Wanting more HP and love that cam chop sound. I am going to start planing soon for a cam install into the late fall/winter. Only upgrades I have now are Long Tubes X Pipe into NPP exhaust and cold air kit. Looking at TSP 224/224 or 224/228 114 LSA cam with springs push rods etc kit. Concern is will I be causing extra stress on valve train by adding a bigger cam and be dealing with more repairs down the road or is this just a install and forget it job?

Those are excellent cams. As long the install is done correctly, and you upgrade the springs, push rods, etc. and get a proper tune, it won't make the car any less reliable. Just remember that with a larger, non-stock cam, you need to treat the valve springs as a wear item and replace them with a fresh set about every 30K miles.

Probably depends more on the lobe style and total lift than the duration concerning valve train stress/wear. Can't vouch for TxSpeed cams, but can say that Cam Motion stuff runs smooth and quiet. I've had a couple of their cams with .610+ lift and am pleased. Just know that any time you increase lift and duration over the stock cam, you have the potential for increased wear. You also need to pay attention to valve springs and be prepared to change them. My current LS3 cam has .620 lift on both sides. Valve springs are BTR .660 lift springs. I'll probably change them at 25K miles. Could probably check spring pressure and maybe reuse them. Doesn't make sense to me to reinstall when new ones are 300 bucks.

If you have a bunch of miles on your LS2, you might consider changing the lifters too. If you do that, you have to pull the heads. That presents an "opportunity" to upgrade them also.

Thanks!
LS2 just turned 52,000 miles and I am definitely changing valve springs push rods etc and a tune. I average about 1,000 miles per year being its not my daily driver. I guess changing valve springs again at 25-30,000 miles wouldn't be bad at my usage.

You can order any cam profile you want directly from Cam Motion.

Specify a valve lift of .585" on both intake and exhaust and your valve springs will last a long time.

If it was my engine (and your not planning on supercharging in the future), here is the specs I would order:

Dur: . . . . . .220° / 228°

Lift: . . . . . ..585” / .585” @ 1.7 Rocker Ratio

LSA: . . . . . .115°

ICL: . . . . .. .113°

Overlap: . . .-6°

BTW .... I don't have the specs of the LS2 OEM cam, but for comparison, here are the specs on the LS3 OEM cam:

Dur: . . . . . .204° / 211°

Lift: . . . . . ..551” / .525” @ 1.7 Rocker Ratio

LSA: . . . . . .117°

ICL: . . . . .. .120°

Overlap: . . -26°

I had a 224r cam in a LS1 Camaro. Drove it 7 years after cam install about 5-6000 miles a year. No issues. Used 918 beehive single springs.

I went with the Texas speed 224r so I could keep my stock stall converter. Very pleased with the power under the curve. With full bolt ons, car did 419/402 on the dyno. 2005 Ls2 A4.

I have the TSP 233/239 112lsa and it will drives and cruises almost like stock with 6 speed. I have hours of tuning to get it to that point tho. TSP lobes are fairly aggressive and would require new springs every 20,000 miles or so. 224/224 is a mild cam for the ls2. Can't go wrong with any of TSP's cams tho. I did install new lifters on mine. You could probably get by leaving the stock ones with your mileage.

If you like the car as it is , you would flip if you drove it with a Yank SS3600 converter.
