So i was adjusting my headers today and i broke the first bolt on the driver side in the head DAM IT!! well im not sure how to fix this i know i have to drill and tap the hole but do i have to take the head off? and i was thinking because i have about $1100 save that i would just get a set of ported heads and put them on there i was thinking tsp stage 1 ls6 heads im not going for all out peformance and an extra 30 to 50 hp wouldnt hurt at all and i dont have the money for a cam right now either so i didnt want to do them both and this is my daily driver so i cant have it off the road for to long what do you guys think? what would you do?

 

if you have the money, just get new heads.

if you dont, either drill it out...or you can ultra cheap and just put on ur headers without that one bolt and live with a little exhaust leak.

 

you can use an easy out to get to it.

 

i did the same thing. i left mine. leaks just a tiny bit i think.

 

Did it brake off flush with the head or in broke off down in the head? If it broke flush or is sticking out a tad , weld a nut on it, and it should come right out.

 

It broke off in the head but i have some money saved for mods so im really thinking about geting a new set of heads and just fixing it while its off and selling it

 

I did the same thing but I just felt it off and lived with the leak(which I never really noticed) And once I had the money I bought new heads.

 

Same happened to me, same bolt/same head and it did leak like everyone else is saying. I would just swap the heads while you have to take it off anyway. If you can live with a small leak for a little bit, do the whole h/c valvetrain swap while your at it. I did, just make sure you don't try to spin a rod bearing like I did also during the breakin lol

 

dont use an easy out...if you break it off in the stud like i did, you're double "f"d

 

Drill it out. But you need a hard drill bit, something like carbide. The bolts are very hard.

And when you get that taken care of, do yourself a favor and get you some GM 3.4 v6 exhaust studs and bolts.




Here's the part #'s: # are 11589154 on the studs, and 11609746 on the nuts

-Thanks to Supersub for the revised numbers
-Original idea was by EVILGMC, so thanks to him for bringing this to our attention.

Note: the studs come in packs of 5, and the nuts in packs of 4
