305 carb to tpi

[C.P.]

I'm pretty sure the intake bolt holes are drilled at a different angle in the heads. On a carb intake you can enlarge the holes to make it work, not sure on TPI. I think the best move would be to use the heads off of the TPI motor.

Carb vs tpi makes no difference on the intake to head mounting points. The difference lies in the age of the heads. Older style heads will have valve covers that bolt on the perimeter with 4 bolts. Newer style heads will have valve cover bolts in the center of the valve cover. If your current motor and donor motor have the same valve covers you're good to go.

The newer style intake can be adapted to the older style heads with some simple hole clearancing with no issues I have heard. But I cannot confirm this personally.

That's right. I forgot about those mid 80's carb-with-center bolt valve cover engines.
