My friend ..you have theeeeeee best early 318 head you can get.
They were only installed on trucks/small rv's in 1967.
Passenger cars received it brother #902 which have the regular exh cross over/closed chamber

#'234' heads have water heated cross over that leaves the exhaust ports blind no longer impeding flow on 2 prots with an exhaust cross over passage.
They also have closed chambers around 57cc's [smaller than the later #302 casting]
I have a set myself and won't be selling them anytime soon.
They are sitting on a 9.1 .020 over 318 w/340 hyd cam and revs 6200rpm all day.

For what they are,Great heads.

Might want to watch the dates on the posts, this one is a couple years old and the dude hasn't been around for quite awhile.

why don't they have an auto delete date or after a certain time they go into a special file.

Thanx
Yeah I read the date, but if someone googles about these heads at least 'they can read the info'.
