i did go look at them and the casting number is 915 as as been said above. here are some pics that ia took. did not make an offer yet as i don't want to screw him or myself. he has another pair of 915 castings that appear to take a smaller valve. here are 4 pics i took. been on this shelf for 5-6 years he said. 1 head says c and other d behind 915. thanks again. just need to figure out if i will/do need them or not. i got lots of bb stuff and lots of magnum stuff and need to downsize. so not sure if i need these but hate to pass if someone can use them. i understand what you are saying steve about pulling a valve spring to check guides.
