The casting # ends in 191. Swirlports.

Correct, only one casting used on those engines from '88-92. The same casting for left and right sides, they are interchangeable from side to side (just to avoid any confusion by Five7's clever line )

Re: Heads !!!

Its not often I get to correct five7kid or Air_Adam but the 191 heads are 350 heads. 14102187 is the number for a 305 TBI head.

That is absolutely correct. I have a set of them in my basement and on my 89 T/A.

This thread I did a while back. YES the 191 head ARE 76cc combustion chambers. It is what was on my reman 350 from Advance Auto. I did online research and spoke with numerous machinists/engine builders. ALL say 76cc combustion chambers.

Yes, I did measure them with a burett and yes they are 76cc, lol.

You will find a number of guys on here telling you that they are 64cc or something different. Well, my 14102191 heads are/were 76cc. My compression was just right around 9.5:1.

Hope this helps.
