[84 400]

had to pull them off because of 2 broken spark plugs (damm rusty plow truck). brought them to the local machine shop and he is gonna check them over and remove the ****ty plugs. They are 1969 heads with the accessory holes. they have different valve springs and comp cams valve guilds. some one did some work to make the guilds fit and that caused the casting numbers to be shaved down. machinist thought maybe someone was trying to run them on a numbers matching engine and cheating or something....

They are double humps with the smaller 194 valves

here are some pictures.




Thanks for all the help!
