I am putting new heads on my engine, and would like to switch to roller rockers at the same time. Do I need to buy "tall" valve covers to provide clearance, or can I make stock valve covers clear ok?

Assuming this is a windsor, you should be okay with stock valve covers. Just be sure to check the valve cover baffles, they may hit. You may either want to remove them, or heat them with a torch and bash them in a little for clearance. ------------------

It all depends on the rocker arms. Most premium aluminum roller rockers will not clear stock FoMoCo stamped valve covers or baffles. We have been able to install some of the no name cheaper brands with small bodies with minor baffle modifications.  ------------------

The rockers I've had experience with are the Crane Energizer rockers (cheapies)

I am running into this problem now. I have a set of Comp Cams roller tip rockers with posi locks and the posi locks are hitting the baffles. They seem to need at least 1/2" more clearence. If I cut the baffle out will I have problems with oil in the PCV or leaking out the oil filler? Will the Moroso VC's fit? I really wanted to keep the stock VC's but I don't know if I will be able to.B-loose

Here's my opinion, knock out the baffles, either die grind off the spot welds or chisel them out. It's good just to remove them because there's always some crud stuck up between the baffle and the valve cover that is impossible to get out otherwise. One thing to consider is most aftermarket valve covers don't come with baffles anyway. I think there's usually a cheap bent piece of sheetmetal that they offer as a baffle. This could be purchased or made and then welded into you factory covers. As I recall the poly locks were what hit on my windsor "Powered by Ford" valve covers too. I removed the baffles and modified them for clearance then re-welded it back in. ------------------

The rockers are going on my 289. I am looking at either Comp Cams roller rockers or Harland Sharp. Any opinions either way? I'll probably end up going with tall valve covers.

Harland SHarps are bricks!  They are about the LARGEST aluminum roller rocker on the market. Nothing wrong with their quality (there are many better and worse), but just their sheer size and weight. ------------------
