Hi, to all 
....
I have a pair of older casting GN1 Heads & Roller Rockers....I have never ran these heads and don't know much history on them...I got these heads and GN1 roller rockers with a package of parts.....
They have minor repairs on the inside of the header ports where the headers bolt on...Also they have what I believe are receiver grooves for use with Felpro head gaskets and possibly some others as well....The roller rockers are 1.65 ratio and are in good condition....I cannot find any cracks or damage to the heads other than the header ports....I would think at the very least they would need to be resurfaced and at that point you could have the receiver grooves milled off...I know this has been done on GN1's with receiver grooves in the past...Was told the roller rockers were purchased separate from the heads and that the springs were used with a roller cam, beyond that have no clue!!
