Default Better valve springs for stock ls1 cam?

Are there any benefits for running a better valve spring than the stock ones for a full bolt on car? I知 getting ready to swap to a ls6 intake and trunion upgrade so it would be nice to get some more valvetrain stability as I知 going to be drag racing... a lot.

The 1218 is a great upgrade and can pick up lost power from the stockers. while you are in there, change the valve stem seals also. And will handle rpms alot better

Ok. I have the 1218s from the cam kit I bought from you last year. Is there an advantage in going to 1.8 rockers?

The 1218s didn't make it in with the cam? Or no cam?

So a 1.8 is not worth any hp? Or not worth it for the money?

If you can do long tubes a cam is on par difficulty wise. I bought an n2o kit and it scared the hell out of me looking at wires and relays and solenoids...ive done 2 cams, one lt1 which is way more involved. The n2o kit is still sitting here. I'm no ase mechanic but I can line up timing dots and set a torque wrench to 18 and 22 lb ft.

youre considering doing valve springs which in my eyes is the hardest part of a cam swap lol. Well, and getting the crank bolt and pulley off. The rest is simple.

and yes, I believe 1.8s are a waste of time when you have a cam sitting there especially since you're wanting to do valve springs...i hate those things...well, locks.

5/16 dowel rods, timing cover gasket kit, and some coolant...and a torque wrench. Ls1howto.com .... Get to it haha.

The 1.8s arent worth the time or money.

I kind of like psi 1511 for a stock cam. Nice and light and very good track record.

it's not that much harder until you consider valve springs in my mind. How hard is it to take out the rad and unbolt a Water pump? After that the hardest thing to do is get the crank pulley off. One bolt torqued to 250lbft is just as bad as some of the manifold bolts and getting certain plugs out with stock manifolds. Nothing is hard and all easy access. Long tubes generally involves a sawzall and getting the car up off the ground. Then getting The exhaust to not leak usually means a trip to the muffler shop. The most time consuming part is valve springs to me. Ls engines are cake since the heads/manifold stay on.

I'm just saying I view the valve springs as the hard part of a cam swap. So why consider those and not a cam when a cam is way less stress in my book.

$250+ dollars for them vs $140 ish for the 1218/1219 doesnt really seem like its worth it. And nearly all beehives weigh the same.

Cant say I've ever had to sawzall the exhaust when doing headers.

IMO, the headers/motor mount job was significantly more difficult than the cam/springs/trunnions/oil pump job.

Ive done longtubes on at least 4 fbodys and it was cake compared to tearing apart the front of the motor and doing valve springs with the motor in the car.
