you will need hardened chromoly pushrods. I ended up going with the Texas speed hardened chromoly 7.400 push rods but every car is different.
the stock ones might work, for 10miles or 2000…but they WILL bend and fold over. Dont take a risk with this shit. Push rods are CHEAP. Once you add the Dual lift springs, all the stress from the extra seat pressure is taking into the pushrods under acceleration…from the extra seat pressure, this will kill your stock tinsel thin rods.
