Hey guys. I just got done installing my MAST 305cc heads and I was looking to install my valve covers back on....and they don't clear the alternator with these taller heads. So, the options are:

a) Clearance the valve covers
b) Clearance the alternator bracket
c) Sell these valve covers and buy a set of Katech covers with a coil relocation kit.

I am not sure who builds these or what they are worth, so perhaps you guys have an idea on which option makes the most sense or possibly you know who built these and what they would be worth resale? Here is a pic of the engine setup with the previous WCCH LS7 heads on it.

If I choose to sell these and buy a set of Katech or if anyone is interested in doing some form of trade, feel free to hit me up. I did not want to do a for sale thread since I'm not sure what I'm doing at this point so I wanted to get some advice/suggestions before making a decision. Obviously Vengeance branded them, but I don't believe they make them in house or anything and on their website they have a different setup pictured for sale.

Good lucking covers. Where is the bolt holes on them?

those are great people to deal with Vengeance Racing .. we used to add there parts on so many cars most of the exterminations racing team has built by vengeance racing the power would be great and hope you enjoy the ride .. if possible add some more pictures of the Z so we can check it up.

good luck with the new setup.

Best,
Mubarak.

They are two piece covers. The bolts that secure the lower part of the covers atop the heads are internal and also place the coil packs inside. The top cover has two smaller screws that attach them to the main part below and they are located on the far edges of the top cover. You can see one of the screws below the breather filter, the others are not visible in these pics. So they have a super clean look in my opinion, but I'm worried about having to "grind" them down for clearance on the alternator bracket. I'm sure I can do it cleanly, but I just hate having to.

I would clearance the alternator bracket way before I messed with those badass valve covers.

I thought the same thing, except I don't want to remove them, nor do I want to shave them in the car and get metal dust shavings everywhere. Plus I have to shave the top cover back a bit since it will interfere with the alternator bolt and mount and I can't shave that.
