The 265's require a C5R style cover. The rocker arm actualy slightly over hangs the valve cover rail. So making the rail higher will not allow you to run stock covers on that. Spacer's are not the answer on the 265's either.
On the 215-255 we have changed the casting to solve clearance issues with stock rockers, so spacers will no longer be needed.

Greg, I'd like to know where to find the C5-R covers. Katech is the only place I could think of that would have them, but the covers they sell do not have the provision for the rockers nor are they tall enough. It would be nice to find someone who sells them. Thanks
GM Performance Parts covers will fit, 12480025 is the part number for them.

Exhaust side looks great. No doubt, this is a very nice setup and is done right.
Mildly ported LS7 heads are looking very nice though.

$6k finished compared without a manifold with something that is untested.
Compared full set of LS7 ($1,500), LS7 manifold ($150), 200 tested sets after GM Racing program log books for seven years. Good for 7,100 rpm's out the box.
Or the new truck heads for that matter for smaller apps..
I just fine the whole thing very rich, untested, with problems to mitigate, no CARB number and delivery...
I think this guys appl., is going to make for a very nice drag car.

BTL FED, I sent Nate some specs and he is gunna see what he can do about "bubbling" the top area to clear the rockers.

Then on top of that, they have absolutly no provision for anything. With all the options I want, the Nasty Performance ones will ring in around $400 and have all the provisions for oil, coils, and maybe some -AN fittings. You might want to start reccomending those before people start seeing another high dollar option to make the 265's work and vere away from them.

Our valve covers can be modified to fit the ET heads and Jessel rockers with no big deal we have done it for a few people already.
We are working on this also I have a set at Harland Sharp he is working on a set of rockers for this application too.
