Just replaced the heads and added a edelbrock performer intake on my 350 and it starts but wont idle at all. I have to keep it in high rpms to keep her running. HELP!!!

rockers to tight?
vaccum leak?
gasket leak?

WAT IS WRONG WITH MY BABY!!!!!!!?????????

 

I think its a bad vacuum leak.

 

It sounds like we are talking about a carbureted engine, correct??? If this is so, once you get it started take your hand and place it over the carburetor, like you are trying to choke the engine, allow the engine to go back to idle. If it starts to smooth out the more you choke it then it would sound like you have a big vaccumm leak.
If the rockers were too tight it would be popping back through the carb.
You do need to check the timing to see if you are somewhere in range and at least set it at 10 degrees, at as low an idle as you can, till you get a grip on what every the problem is.

 

I think its a vaccum leak bro.. But it has something to do with the carburetor
