I am in the process of installing my gt40p heads that i had milled .025 and tfs stage 1 cam with 1.6 rockers. Do i need to order new pushrods or will the stock ones work?
i had mine milled .040, heard this was the safe limit, clayed them to be safe an had to enlarge the notches on the intake side to clear the larger 1.84 valves.
