I just purchased AFR 190 heads and want to use full roller rockers and my stock centerbolt covers. Has anyone done this on AFR heads or any others? Thanks

Yes....I just got done installing my 195's, and I'm sure they're the same as far as rockers and valve covers are concerned.

I'm using self-aligning Crane Gold aluminum rockers (same as LT4 rockers), and the stock centerbolt covers that came on my ZZ4.

I only had to do a very minimal amount of metal work on the centerbolt covers. The bottom corners of each side had to be relieved in order to get the covers to fit over the thick head rails. If you're in the same boat as me, you will need to take out the metal just before the bend in the lip. Leave the bend so you don't lose integrity due to flex. this area removed is about an inch side to side. I had to grind just a little on each oil baffle on the inside. Let me know by tonight if you would like to see some quick pictures, and i will see what i can do. Let me know soon, because I'm going to be bolting them down soon.

Yes, pictures would be great. What cam are you using??

Here ya go...






I made a mistake in my previous post in telling you that it was the bottom corners. It's the top corners as you can see in the pictures. Also, it's the top portion of the oil baffles.

This may very well be what you need to do. But, the first thing you might want to do is to try matching the covers up to the heads before they're in the car. Slap some rockers on the studs and fit things up. I did all the fitting on my livingroom floor, and it makes things ALOT easier than trying to fith them up when the heads are on the car.

Once you get the grinding done, just set the covers snugly on your installed heads with adjusted rockers (don't bolt them down yet), and have someone turn the engine over by hand while you watch for any valve cover movement. You could have someone crank the engine, but it's difficult to see valvecover movement with the starter bucking at the engine (removing all sparkplugs makes things smoother if you decide to crank it over in order to watch for cover movement).

Hope this helps.
