3/8" Pushrod fit in TA Aluminum heads?

[TT/Ameasap]

Can we go to a 3/8" pushrod with TA aluminums?

I don't think so. I may have asked the owner of TA Performance if I remember right when I ordered my rockers. 5/16 will be plenty anyway.

You can but you have to clearance the head to do so. I run 3/8 on most builds I do.

If you are running an aggressive roller cam, you need a 3/8 pushrod to not flex with the springs these cams require. You will also have to trim the valve cover gasket.

3/8" to 5/16" tapered pushrods could be an option for you. I use them currently.
