do i need a choke?

[Shaker455]

I looked at the link and the head in the pic has no passage but I'm going to assume the pic is not the actual part as I used a set of they're BBC 305cc as cast and the pic was not the acutal part either.

So look at your heads for me please and tell if there's a hole where the passage should be?

And yes the fast idle came will work off the electric choke spring in housing and you can set the hi idle speed via an adjusting screw and the choke spring can be adjusted for the duration it's engaged.

As you know HP series carbs do not have all the bosses on the side of the casting to mount the electric choke set up but that can be modified.
