Rocker bolts?
Started assembling my buddy's 408 last night. While checking the pushrod length I discovered the exhaust rocker bolts were bottomed out in the hole. Intake holes are fine because they go all the way through to the runner.
This ever happen to anyone?
Does anyone make a shorter rocker bolt?
Stock rockers, stock bolts, stock rocker stand, CNC'd edelbrock heads. Gonna call the shop that built the heads today. I could always cut off the unthreaded tip of the bolt to make it fit, although I'd llike to find another solution.

Well, I talked to the shop that cnc'd the heads. He said they never heard of this problem. He said Edelbrock drills and taps the bolt holes. They have seen holes that werent threaded deep enough, and they just tapped them. These are deffinately bottoming out in the hole though. He said he could give Edelbrock a call for me, but I decided to just cut off the tip of the exhaust rocker bolts and all is good now.

edelbrock sells shorter rocker bolt kits for their ls1 heads, look on ebay, i think lingenfelter sells them on there. edelbrock #8597 only comes with 8 bolts so you would need two kits.

That would have been great to know last week. LOL I asked around and couldn't find any other than stock length. I only cut the 8 exhaust bolts. I even asked the head builder. Oh well. Engine is all assembled now. Thanks anyway.

This was a problem on the early batches of castings. It was done by Edelbrock at Lingenfelter's request. It really screwed me up when I first found this issue. As mentioned above, the fix is to grind the tips off your bolts or use the shorter Edelbrock bolts.
Good luck with the Edelbrock heads. Please post up your results and impressions of them when your up and running.
Cheers,
Richard
