:Also Adams suggestion on Magnum heads is very good if the X,J,U heads are not found. On a 3-8-teen, or any small block (In general) there likly to perform better due to the closed and reduced cc head chamber.
which will prefrom better the magnum heads or the X, J, U, heads? Where do megnum heads usually crack that way if i find a pair i can check,could jsut get magnum heads until i find X,J,U, heads, ill have to look around the wrecking yards here.
my carb is clean, my valve train does make some noise when its running, timming chain could be another possiblity ill have to check.
