Now I know why everyone always told me I'd find out when I measured it.

You can check similar installs and that should tell you, but in the end I bet you'll end up playing with an adjustable pushrod.

 

I cant find anyone that has this big a cam on a lq4 bottom end

 

With what heads and gaskets? If our using stock heads and gaskets then yes it'll clear. Milled heads, larger intake valves, or thinner than stock gaskets will require valve reliefs. But as stated above, it's always best to check PTV for your particular setup.
