Heads for mild 360 build

Yep.

Pick your parts, pay your money.

Even if you bought the SM's and had the VJ fixed, you are going to be in for a decent sized bill with reconditioning J heads with new springs/retainers/etc.

What's the all in cost to run stuff. If it's 700 to run one thing and 850 to do another, not a lot of difference. Spend a couple minutes on each bowl of the SM head and it will make 400+ at sea level with the parts he has and a xe268h type cam.
Yeah, certainly many ways to skin a cat. If I were the OP, because I have the J heads already, I would start with inspecting them. I just did a small block set of heads - new exhaust valves, new springs, 3 angle valve job, and cut .030 and my bill was just under 500 bucks. Guides were all in tolerance. Now that the black Friday sale is off, those SM heads will ring a 1200 dollar bill - and need studs for fully loaded heads. Still not a bad price, but just say'n.
