this is my first motor swap in my ef 4dr, and i want to make my motor faster without adding a turbo or sc setup. my first question is that i want to machine the head, how much can i shave off b4 my pistons hit the valves and work properly? does any one make cams for this motor? i have checked everywhere and only found cam shafts how much of a difference would b into changing the shaft? i was looking everywhere and i only found a few people that sell zc parts and all of them were sohc. a list of dealers would help alot too. (i work in a machine shop so ill b machining my head)

 

You should be able to take quite a bit off the head.

A few companies make cams.

I'm using Rocket Motorsports regrinds and valve train in a customers A1 build.

All depends on how much you want to spend.

 

alright well how much am i able to take off? if u know cuz i have been searching everywhere and i came to the conclusion that that kinda info aint out there or i just dont no how to search lol. but basicaly i want a few mods that would help my motor the most compared to how much it would cost. if u get wat i mean

 

Up to .080. Some modification will have to be done to handle it. Anything more than that I'm not sure about. There is a thread about it on OCO.
