Thanks Guys! I'll try AutoZone and as a backup, I was able to find them (using the name) at
www.bowtiebits.com.The 2 studs that hold the intake on top of the exhaust were really rusted and snapped-off when I turned them. Are those absolutely necessary?
Thankfully the ones actually holding on the manifolds did respond well to the penetrating oil and came out without issue.
