'78 pcm 351.
All connections and distributor are out and valve covers off. It looks like the heads can be removed with the intake still on...is that true? Also, do the rockers need loosened? Thanks much |

No you cannot remove the heads with the intake on. Yes you can leave the rockers tight but if it’s going back together better to remove them and the pushrods - tag and bag before removing. Otherwise push rods fall out everywhere

Push Rods, Rocker Arms and Lifters need to go back in the exact hole they come out of or you are asking for failure. If you plan on re using the old parts. These parts all wear in together and if you mix and match them you start a new wear pattern that many times leads to failure.

JoeinNY and MrMcD is correct on their statement on rockers,
pushrods and lifters. I have always loosened the rockers and remove the push
rods when removing the heads off an engine. Even if you are changing out the
head gaskets, replacing parts or If you’re going to have heads reworked, you
going to have to adjust valves. |
