i have a set of chevy 350 heads that today i was going to put brand new intake and exhaust valves
that the stem measurement was 11/32, but when i went to slip the new valves in they didnt fit. then i looked at the heads more carefully and seen that they have a sleeve in the valve guide, i measured and its a bit less then 11/32, i looked in all my parts books and can t find any valves smaller than 11/32 ???? does any one know what happen to my heads or are there special valves for replaced valve guides in the cylinder head,or do i have to take them to the machine shop to get 11/32 valvew guides in it???? here are some pics. left is the new 11/32 exhaust valve, right is old exhaust valve with unknown stem size
other pic is intake port with sleeve like thing
