when i loosened up the lower intake bolts the front driver side acted a little tuff but came out....when i pulled it out i noticed only half came out.....so think i can drill it out or should i look for new heads???
How much can you see in the head? Is it right up flush with the hole in the head? Basically my question is can u weld a nut to it? I have done that in the past it works great depending on where it is broken.
that blows goats. the exact same thing happend to me when i did my manifold swap. both front lower bolts broke off in the front of the heads. i tried to use the bolt extractors to get it out but the bolt was too rusted in the head. i got the titanium slow speed drill bits and slowly drilled them out until the the bolt came apart. then i helicoiled it. works fine now. however if i had the extra cash to get those gt40s that would definatly have been an excuse to upgrade
I had a set of GT40P heads that I sold that had a bolt broken off in them. If you use a small enough bit, you should be able to drill it out, otherwise a machine shop could do it for next to nothing. I had one quote me like $35 to extract it, but I was able to get it out myself.
