BB 402/454 head casting 353049

[59Fins]

353049 head, what would this head come out of ? New here, I found on other sites, used 70-73, appears these are 73 by date code, March 73. Most likely a truck by 73?
Friend of mine has these on a 67 396, they were on car when he got it. Any info is better than none....... 113cc

Pretty sure 049's are 122cc not 113 they look like 781's ... they cast a little relief (a radius) by the exhaust valve.
Pretty sure these were pretty much just used on 454's probley be a good stroker motor head too.
