took the heads off the 413 and thay are 2406516-7 closed chamber. wasn't exspecting to find them on a 64 413. i always thunk thay were a 361/383 head. am i missing something?
on a happy note ... took the heads off the 68 383 and there 906 heads. sadly has a big hole in a cly so much for that block.

wonder if the 64 361 i got for my 62 will have them?
i will be bringing the 906/452/516's to carlisle with me
 
something i should add.. the 463200-4 heads don't have a rocker shaft cast in the head like the rest do. its late 50's and got it just for the stuff on the outside of the mill and the ajustable rocker shafts thinking thay were like the 64 up stuf. when it got here the beackets and rocker shafts were gone. guy swears to god thay were on it when it left his place.... but sense it was the old style shafts guess it don't matter....lol
 
The 516's were used on most Mopar BB. I think starting in '63 or 64. Can be a really good head with mild pocket porting and the larger 1.74 exhaust valve.

with the flat tops in the 413 im guessing it probly won't run well on the pump gas of today. if the slug wern't zero.... it wern't more than 2 or 3k in the hole
