I have the chance to buy an 88 305 motor which had the TPI set up, my car is a 1982 indy 500 and i want to keep it stock

My question is will the CFI inlet fit the later heads, Please note i live in the UK and we don't have an endless supply of used parts for american motors here

 

The angles of the center intake mounting holes will be at a different angle. You can use a die grinder to wallow the intake out a little to get it to line up. Otherwise, should match up.

 

Trouble is bolts under manifold lid are exposed to vacume and likely difficult to seal properly long term when they are not screwed down to a flat surface,One possibility I had thought of when I was thinking about trying #193 heads on a CFI was to drill out and tap the center holes for 1/4" pipe plugs,install the plugs,then locate holes and drill and tap the plugs for the 3/8-16 manifold bolts

 

I'm posting this to demonstrate that it may be an accepted practice to elongate the holes as this intake already comes that way. I wish they had a better picture of this Weiand 90748 showing the actual bevel on the spacer.
