Engine help!!!!!!!!!!!!!!!
I have a 92 with 351; I removed the emissions stuff and was in the process of putting on headers when I broke the last bolt. I tried easeout and broke it so now I'm tearing it down to take the head off so I can drill it out. Before I started this the compression was 130-135 on every cylinder. Now that I'm pulling both heads. Figure since I got to replace one head gasket I should change the other. What do you guys think I should do with the heads: take them to the shop or just fix the bolt and put heads back. I plan on checking for cracks and checking head to see if it's flat. But beyond that should I do anything else. This is my daily drive so I need to get it running asap. But now that I'm this far into it and going to have good heads going back on should I worry with the bottom half? Kinda worried about timing chain also basically convince me to leave this thing alone before I rebuild the whole thing.

If you can get a die grinder or even a dremel with a carbide burr tip, you can get in there and grind out the broken bolt. Then its just a matter of seeing if you still have enough good threads or if you need to heli-coil the hole afterwards.............Save you a lot of work, unless you really want to pull those heads..........I have never surrendered to a broken bolt yet!

Have no idea bought the truck couple years ago used it for work just recently I sold my daily drive to convert this into my daily driver. The odometer says 216000 but have to believe motor had some work to pull compression numbers like it did.
