I have a set of standard merc BBC (502 mag) valve covers. I am looking for an aftermarket set that will clear a Gil exhaust system (with roller rockers). Thanks. (716) 807-4561 Jim

I was interested however I have gils or they are being shipped and I have R/R's also and am in the same situation you are. Do you know what WE are both going to be in need of. If you don't mind sharing with me I would appreciate it.
Thanks,
John

I can sell you Eddie Marine Valve covers they will work for your set up. Check them out on eddiemarine.com part # 108-02P. They are polished but I can get them any color for additional cost. I'll sell them for $207.99 a set. Let me know, Jeff @ J&J Marine 856-228-4744

We offer these covers http://www.keitheickert.com/detail.aspx?ID=919 for $179.99 These will do the trick.

Thank you guys. I will check these out this evening. Any deals on shipping????

Stock Merc valve covers will clear roller rockers and Gil exhaust just fine. The valve covers on the 500HP are the same casting as a 454mag. You just have to grind off the drip tabs and possibly radius the corners on 2 rockers. Thats what Merc does.

what about the 330's valve covers they the same? I'm thinking they are a little shallower. Can't remember at the moment. Concerning the R/R's

A friend has a set of polished imcos that will clear rockers and exhaust. Pm me if your interested about $100.00

I'm 99% sure they are all the same.

I have a couple sets of aftermarkets here that I will sell for $50 a set. The have tall breathers on them.

They either are etched or have a plate with different engine builders names on them.
