OK, so after spitting a valve into my piston, it was time to build a new engine. I picked up a pre-87 350 and stroked it to a 383 and put Dart 2 angle plug heads. Being that I just slapped brand new custom exhaust on my K5, I wanted to use my old engine's manifolds. So I go to slap the manifolds on and the stock 350 ones wont fit!?! The new heads have the exhaust ports too close together or far away (I can't remember which). Anybody have experience with this? Will I be able to buy a set of headers that will bolt right on? Thanks ahead of time for your help!
