The title pretty much says it all. I'm getting ready to pull my motor (long story, lost oil pressure and now it knocks) I have aluminum heads, and I'm a little worried about hooking the bolts into the heads to yank it out. I have pulled a motor and tranny before, but on a car w/ cast heads. Also my tranny weighs 50 to 75lbs more than a t5. Should I worry about pulling out the threads or anything? BTW I'm talking about using intake bolts to pull it.
