Bugs me, too. I'm still debating over whether to clip the frame or not, but if I stick with the stock rails they'll definitely be smoothed up.
Which cammer is that, btw?
Its a resin cammer I have had for a while. basically the thunderbolt block and I think jo han cammer top end. those are about the closest valve covers out there for one. front cover is from the drag version of the 68 GT500 from amt. its a mix of cammer parts from everyone put in one resin pkg lol
