head install with arp 12pt
k the deal is I installed my arp 12pt head stud kit today and did like the instructions said I hand tighten them into the block then after gasket and heads where on I torqued the nuts down to spec in sequence and in three sweeps 22lb on the tops and 80lb on the middle and bottom ones after done I looked at them and some of them stick out of the top of the bolt farther than the other one sticks out pretty far what should I do remove the heads and redo everything?

Sounds like you might have messed up screwing the studs into the block. If you didn't make sure there wasn't any water in the bolt holes it could of felt tight but not seated all the way due to water/thread sealer in the threads.

they are the right bolts im sure of that i ordered them based of the head bolts i took out which had the shorter ones in the middle row on both ends. so should i take the heads back off and recheck over everything?

2nd picture looks right, the others look like they are out too far. You might be ok if you take out each stud that is not installed all the way one at a time, clean the threads, remove the water, and then reinstall the stud. They should all end up having about the same thread count above the nut once installed properly.

so I'm thinkin I should break them all clean them all out and reinstall using the same process. Would I be ok doing this since the motor has yet to be ran? And will the gaskets still be fine since they are new?

It looks like an Iron block to me. Am I correct in thinking that? My brand new iron block straight from GM had a fair amount of powdered surface rust on the last 3-4 threads in nearly every hole. If I put them all in hand tight I would have had the same problem as you. I had already thoroughly cleaned the holes as best I could. What I did is thread them all in hand tight then put an allen on them and tighten them down slowly. Every 1/8th of a turn I back it out a full turn and then tightened back until it stopped then went another 1/8th of a turn. When it finally bottomed out I loosened 1/4 turn and tightened 1/4 turn about 5 times. After that I could thread it all the way in by hand very smoothly. After that process I pulled a stud out and there was a fine dusting of rust on the last 3-4 threads. It looks like the ARP's have a much sharper cut on the threads even though they are the same pitch. Because of that they dig a little deeper into the threads than a stock bolt. It's tiring but when it was all said an done my studs look perfect.
