  • changing heads for higher compression

    does anyone know if you can put vortec 350 heads onto a 1969 chevy 350. the reason i'm asking is that if i can do this that would raise my compression ratio to 10.5:1 just right for the propane conversion i'm wanting to do. but i'm not sure if there are any hidden problems in it. if you have done it or have heard about it please reply. thanks in advance

    yes, BUT:

    you will also need an intake manifold machined for the vortec heads. The older style intakes do not fit.

      i thought that i might have to do that. i will also need to change the pushrods won't I? any other things that might become a hassle in the middle of the project?
