318 combo

To resurrect this, I've decided to go with the EQ heads, but I'm trying to figure out rockers, etc.

I figured I might as well change the cam and lifters while I'm doing the heads, so I'll grab the Howard's cam & lifters suggested above. I'm not sure about which rockers and pushrods to use. My block is stock height - is there an aftermarket pushrod that I can get or will I need to measure it once assembled? As for rockers, is there a cheap 1.6 option that anyone can suggest?
