That seems wrong to me. You would think that would cause a slight leak since the rocker bolts aren’t installed with thread sealer. But in reality, maybe even OEM unported heads have the bolts protruding and we just don’t know it?

My TEA 5.3 heads on my camaro did this. Tolley did some pretty serious work on them. Just make sure you put some sealer on the threads or they will leak. I had to take mine back apart and put the sealer on it...

I don't think stock heads have it protrude to this extent but I know you still have to RTV them so there's no oil leakage. The shop is going to replace with a slightly shorter bolt and call it good. Wonder how much performance this could kill.
Just surprised there isn't more info on this or the CHE kit doesn't come with shorter bolts.
What’s interesting to me is that like you said, the stock bolts must protrude a bit- I doubt they're machining 1/2-3/4” of material there- yet there’s nothing said in the service manual about using thread sealer on the rocker bolts. Or RTV. I haven’t heard about using either until now. Granted I’m talking stock unported heads but it seems those bolts would be protruding on them too, just not as far.

I have an untouched 862 on my shelf on standby for if I drop another valve. I'll look to see if there's a holt protruding tonight, but I don't think there is. The book that I read about it in is the one I've recommended a few times on other threads, I'll try to post the segment referring to this tonight as well.
Yeah these heads a junk I'll probably put another set of 862s with 2" valve cut into them since they are such power houses.

99% sure they aren't protruding in stock form but there is a dimple you will see in the runner. When you port them, they cut that out.

Made a stop by my buddy's shop during work hours and in an incognito work truck to catch him off guard and give him shit for not starting my axle. Well, he surprised me and it will be done this afternoon! Seriously an awesome dude to work with. Can't pick it up until tomorrow unfortunately but I should get some teaser pics tonight.
That makes sense. I couldn’t see them removing enough material but if there was a big bulge where the bolts are then yeah. Otherwise you would have to use thread sealer on a stock setup and you don’t. Sure seems like these companies doing the porting would be sure the buyer knows that.

Didn't get home until way late so I didn't have time to check on anything. Spent a couple hours actually helping lay the powder for my axle. Wasn't allowed to take any pics or videos of the process but it's pretty awesome if you never seen it done. This is a 3 stage powder with very specific heat cycles and cure times, pretty scientific stuff.
Anyway here's some indirect vs direct light differences. I think under the truck it will appear black 99% of the time but if head lights or something hit it then it will look cool.

should look good with your underglow kits
Powder coating is actually really easy to do, you just need the right equipment especially an oven big enough to hold your parts. Its a lot harder to mess up than paint.

Good I'm gonna change my plate to BR0D0Z3R too.
Its surprisingly simple to apply, it puffs out so gently and covers so quickly with the static charge. What surprised me is the powder that has the gold color is white as a sugar booger but as soon as it melts to the hot metal its thats brilliant dark gold. Then the cure time is super short and it's ready to do whatever as if it had cured and hardened for days. Cool stuff

Well, it's been nearly two years since I pulled the perfectly good 4.8 out of this truck and it spiraled out of control to the point it's nearly stripped and needs a lot of work. I'm finally starting the rebuild and going in a different direction than before in a few areas. Here are the basic run down specs of what it will be.
The current engine specs
-LQ4 bored .055 over
-PRC 220cnc ported heads
-Forged pistons but stock gen 4 rods and crank
-9.7:1 CR
-222/234 .615/.600 113lsa. (Cannot wait to hear it!)
-ARP 2000 studs
-Stock rockers with CHE upgrade
-TSP platinum .660lift dual springs
-TVS1900 with a variety of 8 rib pulleys
Drive train and suspension
-NV4500
-Stock 4.10 front diff
-Hummer H2 14b SF with 4.10s and an E locker.
-Deavers springs in the rear
-Bilstein 7100s in the rear
-Fox coil overs upfront
-JD Fab UCA
-8 Lug factory forged Ram wheels and 35s

I got the H2 axle home last night and popped it open and I am happy with what I've found so far. The oil looked golden and very clean! There's minor rust on the outer edges of the ring gear but I don't think it's an issue.
Can’t wait.

You and me both it's gonna be a while I'm hoping it will move under its own power by summer.
