Default New LS3 Scoggin Dickey Heads w/ Holes in all...

8 intake ports. What the heck! You can really see it in this picture. I'm holding a light outside of the head to highlight the size of the cracks. All 8 intake runners are exactly like this. Anyone heard of this before?

after doing some research, I guess this isnt abnormal. It just struck me as pretty scary. This is my first set of ported heads. Guess I just need some rtv or permatec

If it's where the rocker bolt goes it's normal for all cnc'd ls factory heads.You'll need to add thread sealer to the threads of the intake rocker bolts.I have a set of the shorter eldebrock rocker bolts to use with cnc'd heads so they don't stick out into the runner.pm me for a price.

The stock LS3 casting has a huge bump in the port right there for the rocker arm bolt...it's going to be a hole on LS3's ported by just about anyone.

Yep normal for ported heads. Now if they were stock, then you'd have a problem.

Yeah, its exactly where the rocker bolt goes on all 8 ports on both heads. The thing that was really weird is that I called Scoggin Dickey right before I made my initial post, and bitched at the guy. He acted like that wasn't normal at all. However, the guy I spoke with didn't seem to be too technical, so he might have just been a customer service guy.

My bad, I am not used to seeing that in gen 3 heads... guess I should have read the title a little closer

Yeah, I would have been shocked as well. But I guess if it's normal and the bolt seals it. Doesn't seem like the bolt would be the smoothest surface though.

Part of the final setup is making sure the bolts aren't too long/protruding into the port, and if they are...correcting that too. Shorter bolts if necessary.
