Do the Victors come with the springs you need to work with your cam?
Will those used heads require a trip to the machine shop prior to installation?

With only that minimal amount of work, if the Victors have the newer style chambers, they will be way down on flow compared to the TF270’s, especially in the low and mid-lifts.

Depending on what you do for rockers, there could be a few hundred $$$$ difference between the two.

I’d look into exactly what the header fitment situation is between the two so you really know what you’re getting into.

This is really good advice^^^^^^^^^^^^^^. J.Rob
