360 Magnum Build w/ V Belt Configuration Question

Have you talked to PIE about these heads? That is the same description they used when they were preparing the good Engine Quest heads that were cast in New Zealand. Do not trust any advertisements right now about cast iron Magnum heads. Most places still have the same info, but they are using the stock style replacement castings, since nothing else is currently available.
Is there a problem with the old heads on your engine? If not, just run what you have and save your budget a bunch of money.
Well visually the heads seem to be okay but I haven't had them apart. But as things do, this engine build has turned into a different direction. The stock heads are not going to work for where we're headed. In talking with my machinist who I've worked with before (quite a few years ago he built a 360 LA motor for my wife's 'Cuda, that thing was freaking hot!).

There's a .001 difference between the piston and bore so at this point we're looking at 11:1 pistons, I beam rods and coming up with a cam combination. I've had to reel him in several times and remind him this is a street engine for my daughter :steering:

I did actually call PIE and talk to them about this head. But it was more about the flow and work that has been done to them, but not actually where they started from. Another machinist vouched for these heads from this company as he has built a few magnum motors and used them. So, we started looking into it but haven't made a definitive decision. Like I said, right now we're putting together the bottom end combination so we can work our way up.
