Question for anyone who has done 4.3 vortec head swap

[GDiddy99]

Hello iboats!

I'm wanting to do the vortec head swap on an 89 4.3l and putting a 4BBL on, and I'm thinking it should be pretty straight forward except for the ESA and throttle brackets. For those who have done this swap, what did you do to mount these since the new intake is different? If you have pics of your work, that would be great!

I haven't done one, but I looked into it and you need to look at how the head bolts are. I believe that there was a difference with them.
