I got my old manafolds and y-pipe off. But I got one bolt broken off in the head.

Im Curious what my options are dp i have to pull the heads off and get them fixed. If so how much would that cost.

Should I go ahead and order the 330hp crate from gm?

I dont want to put to much money into the engine itself cause I had been plaining to replace it.

the slp headers and y pipe looks like they will make a huge improvment over the stock.

 

Im sure there is a way to get it out with the heads still on the car, but if you take it to someone to take out it wont cost you anymore than like 30 bucks

 

Go to the local auto parts dealer and get a bolt extractor. Its not expensive and you can do it w/ the head still on the car. Basically you drill a tinny hole in the broken bolt. Then a little bigger hole. Then you insert the bolt extractor into the broken bolt and use a wrench to back the bolt out. That simple.

 

it's the one all the way back on the drivers side so i cant get a drill on it. So off the tpi come and then the head.

 

IN that case, port them heads while you gots em off

 

Depends. Were you planning to replace it next month or next year? Would it be more convenient to replace the engine now or later? If you do the swap now, will it affect things like food, shelter, other necessities?
If it were mine and money was not the primary concern, (usually is for me) and I didn't have to drive it to work tomorrow, I'd probably be tempted to swap it out as you are.
Just some things to consider...Do as you like.
