i picked up a nice set of GT40 heads (non P) awhile back for a good price.
im finally getting around to cleaning them up. my plans are nothing radical, no porting or anything like that. i just want to clean them up and run new valve springs.
but where can i get stock replacements or better quality valve springs. if anybody knows part numbers or dimensions on these that would be great. thanks
