Coming together nicely!!
Is the .666" lift including the 1.8's? That rocker issue is pretty common with low covers. The new Comp aluminum rockers have several of them in each set rounded just like yours for the same reason. Harland Sharp makes a good rocker.
Don't forget to test fit your headers before installing. Seems like folks always have to do a little flange grinding on the bottom edges to clear the lower head bolts on the Edelbrock heads.
Keep giving us updates! I'm waiting for the one when you stuff your foot in it!
What carb and intake? I can tell you even the hyd roller versions of these like good airflow. A buddy with a very similar one with GM/Edelbrock rectangular ports, a smaller hyd roller and 9.5'ish compression picked up 30 RWHP with a Holley Strip Dominator over a factory 427/425 type aluminum intake.

I have the Holley Strip Dominator for the intake, glad to hear your success with it since I was wavering between it and the Perf RPM intake - hopefully it fits the L88 hood I have. Originally I had a 4781S carb. I bought a QFT '1050' main body & took the parts off the holley. A poor man's version of the hp1000 I guess. Speaking of which, I loaned it to a buddy to try on his 496. I've got to check how it worked for him & get the carb back.
I should get the intake and valve covers on this pm. Thanks for the tip on the headers. I know when I would have figured that one out. . .

Done!
I finally had a bit of time this last weekend and over the past couple of days.
I'll post a few more pics & do a bit of a write up later. . .

I mentioned earlier there was an oil pan fitment issue. The pan in the pictures is a second one I purchased. The fitment issue was with the lip around the rear main and the two rear bolt holes. the rear seal lip and bolts are a separate piece welded into the pan. Moroso didn't get this in their jig correctly IMHO which was why it didn't line up on my block. Even this one was slightly off, a little less than 1/16". A couple of blocks of wood and a few taps with a 4# hammer and it lines right up. This was another picture I had on my SD card that puked, so here's a shot of the area with the second pan installed.
Not the best pic, but this area was about 1/8" deeper in the first pan. I checked it against the two GM gen 6 pans as well and they fit perfectly. I ended up shipping the first pan back to the same supplier I bought the first one from, marked as defective, since the folks at Moroso weren't willing to exchange it.
The headers are actually a friends, though I've the same ones sitting on the 454 in the car. And when I pulled them out of the box, there was this:
I spoke to the folks at Hedman, sounded like it shouldn't be an issue to get them exchanged (it BETTER not be). Stay tuned. . .
