I highlighted a statement in your post. If what you said about the pushrod length is true, that is probably part of your problem. BBC pushrods, because of the valvetrain design, are not all the same length. Over the production life of the BBC engine, the lengths vary somewhat. Exhaust pushrods are longer than the intake pushrods. They will not interchange.

Thanks. I miss worded that. All the intake are the same length. All the exhaust are the same. Someone had asked about different lengths.
The guides are Comp Cam I purchased from Summit. Definitely a learning moment for me with this 454.
