All...just put the car back together after installing some 264 cams, valve job, ported intake head, and ati crank. Started up but there's a ticking sound...any ideas?

It sounds like you forgot to put some of the shims back into the valve buckets. Remove the valve covers and check to see if you have all of them in their places. The shim is what's sitting on top of the second bucket to the right in this picture.

spark plug wires?

Shims should be in place, had a local legit shop put the head back together after the porting. Spark wires are in.

So, if the shims aren't right, then its the buckets that are hitting the lobes on the cam shafts, right?

That doesn't mean anything, no one ever knowingly makes these types of mistakes. Don't defend it, just go double check it, takes ten minutes.

If the buckets are missing the shims, then the lobe is hitting the buckets top, not allowing the valves to open up all the way.

Ok...they all have shims. Any other ideas for the ticking noise?

That would've been your cheapest resolution... whatever it is unfurtunately... will be catastrophic.

did you tighten the cam gears? and the water pump pulley.. i know random things but once i forgot to tighten up the water pump pulley and it made a ugly sound... just throwin ideas out there.

Yup all those are tight. The noise is coming from the valve covers. From what I've read, could be something as simple as low oil pressure or low oil. Car has plenty of oil but haven't checked oil pressure yet. What if the shim clearances are off...could that be causing the knocking?
