hello, i removed the bolts that hold the exhaust manifold to the heads on a 1998 3.3 V6 and now i'm only able to get a few of the bolts back in, there are 4 bolts that will not catch so i can thread them in, nothing's broken and the threads look fine, are there any tips or advice in getting these bolts to catch thread so i can put them back in??

 

if the holes don't line up the manifold is probably warped. chevy uses this tool to line them up. not sure if it would work for you without seeing the manifold
