Ok well as far as how do I plan on getting the clearance needed to run that much lift all that is needed is for the valve guides to be machined down so that you won't have any issues with the valve seal comming into contact with the retainer and causing oil ussage issues ect.Or you could possibly use modded retainers.But the only modded retainer kit that i have seen can only have lift up to .595 and that was the one from thrasher.
I do not know how much piston to valve clearance i will have but plan to use some clay to be on the safe side.I have not heard of any issues with PTV clearance with any cam although there has to be a limit somewhere.
I want a bad ass street build. What do you think would be some issues if i did run the is4 on the street?
What would be some issues that i might be seeing when running it on the street is what im asking.
