Buick v6 race motor

[1bad85gn]

I came across a deal on a buick v6 race engine and wondered if anybody had any info. The motor has an aluminum 4 bl. intake. It has roller rockers and the heads appear to be aluminum. The heads also have the number 10090 on them. The block has the # 25506397 andc 26. Anybody know what this is? will the heads work on a GN? Is the block / crank worth anything? Any info appreciated...
