I just got my New ( old stock ) Holley systemax heads today. I got them off of ebay bare. But there are no spec sheets or anything with them and I cant find any info on these as far as valves. It says they are 1.60 and 1.90 but is there a stem dia and length I need to know.
I bought them because they were cheap ,,and they didn't require Aftermarket Studs and rockers and pushrods, I can use all my stock stuff for now.
anyone else got these , or know where I can get info?
