Best way to spend last 600 bucks

Damn are those roller rockers 600 bucks?????????? I have found that the Magnum stuff is significantly higher overall than LA stuff. I'm paying a pretty penny for a roller cam and better quench. The next motor will be an LA 408 with a flat tappet for a lot less than a Magnum as a platform to build up.

No suggestions on spending the last $600, but I will speak to this. Have a good machine shop drill and tap the Mag heads for Chevy studs and get Chevy rockers. Even Harlan Sharps for Chevies are cheap!

Curious, what costs so much more with the Magnum??
