Default Cylinder head help please

Hi Iím looking into building a 1776. I have two sets of 1600 cylinder heads one pair part number is 040 101 375 13 and the other pair is 113 101 375 A
Just wondering if there is much difference between them? Any advice would be much appreciated
Thanks Dan

The 040 was a Brazilian VW head, think they had a step machined in though which your 113 wont have.
Both 35x32 valves.
Check the chamber volumes, guide wear and base your decision off that.
