Need Lt4 heads and valvetrain
 

I recently bought a Lt4 ported intake for a lt1 build I'm going to be doing. I'm having a hard time finding a set of Lt4 heads, and I also need a cam, rockers, and springs. I'd like to find a used cc503 or similar grind and a set of 1.6 roller rockers (preferably self aligning) . Let me know if you have anything I might be interested in. Thanks
