I want to purchase the 1.6 roller rockers but I am unsure on which ones i will need to fit my LT1, i also want to purchase new pushrods but unsure of which ones to buy, and im sure with new rockers ill need new valve springs

so if anyone can recommend which ones to buy i would greatly appreciate it

Looking to do this budget or are you willing to spend a little more now and be able to reuse some items when the mod bug bites again later?

Personally if I were in your shoes I would look at the "do it once" aspect and get 1.6 Comp ProMagnums NON-SA 7/16 , get new rocker studs 7/16", and GM guideplates. The stock 94 pushrods are hardened so you can reuse them for this mild setup and the LT4 springs are cheap and would work well for 1.6s on a stock cam they are not as well suited to the HOT cam as one might think though.
If and when you do a more serious build pushrod length will need to be checked and may very well vary from stock hence not recommending going all out on them right now.

If looking to stay cheap I had good luck with ProForm rockers on a ZZ4 cam which is about halfway between stock and the HOT cam. Get them in 1.6 SA and a set of LT4 springs and you can do this project for well under $250, I wouldn't trust these rockers on a more serious cam though. I put like 50K on mne though 30+K of that with the cam.

Agreed.

We also need to know how much power you are putting down. In many cases the $30 hardened pushrods are just fine, which people dont seem to realize.

Well then your right at the border line with pushrods. 94's actually come with hardened pushrods stock so you should be fine. This also depends on mileage. Im having a H/C package being put on right now and I should be around 400rwhp, and my car is a 94 like yours, but has only 60k miles, so I stayed with the stock ones. Some people might want a little more reinsurnace and buy fresh new Comp hardened pushrods ($30) but they are pretty much the same as what you'd have now. Then again you could always spend $100+ for a chromoly set which is alittle overkill IMO.

AI can help you out with all the valvetrain stuff, that is where I got my rockers/studs, pushrods, guideplates, springs, cam. Since you are already dealing with them let Ron help you, their prices on this stuff are good and they will makesure everything matches appropriately.
You are going to need to check pushrod length anyway with all the chang3es happening it is not wise to asume the stock length is still right though you may find that to be the case.

The Competition Cams rockers are really nice.

The later stock pushrods work just fine. And don't waste your money on the 7/16 studs. You will need to be running a lot more valve spring than the LT4's to have issues with either.

Good Luck,

He is looking to go with an AI package not that those are that radical but in this case he can go bulletproof for little extra cash think you would agree that why not do the 7/16ths then????

If just doing rockers and springs with no future intent to go further I would agree no need to consider the larger hardware, had this detail be clearer in the first place I think the replies would be more in agreement.
