How much bigger depends on what kind of chance you want to take on the cylinder wall getting to thin. Without going to special made pistons you have a few choices.
Use 3.5625 pistons and sleeves for a SH and bore the H block about .125. That gives you 169 CI. Use 3.625 pistons and bore to use the pistons without sleeves. 175 CI. If the sleeveless bore in the H block is good and you can get the correct cylinder wall to piston clearance the 3.5625 pistons can be put in a H without useing sleeves. To use 3.625 pistons with sleeves the H needs bored to around 3.750. Some won't do it without problems.
If the tractor is going to be used other than pulling and you decide to bore. Think about the 3.625 on the block. Then if another rebuild is ever wanted bore just a little and install 3-9/16 pistons and sleeves for a SH. Or if they work for your block use 3.562 pistons without sleeves, then the sleeves for 3.562 pistons in a SH if the bore wears out. Or bore again to use the 3.625 pistons.
Don't know what cylinder head you have but some pistons for the bigger bore will contact a H head unless the head chamber edge is rounded a little. Filler rings or special head gasket maybe needed for some combinations.
Also if any machine work is done the parts that are to be used size is needed, or better the parts on hand and measured.
Block bores without sleeves will measure around these numbers or a little larger. H block 3.5625, C-164-3.6875, C-169 and C175- 3.749.

Today's Featured Article - Uncle Cecil's Super A Lives Again - by Mike Purcell. A week or so out of most of my childhood summers was often spent with my Uncle Cecil and Aunt Sissie in the small East Texas town of Maydelle on their 80 acre farm. Some of my fondest memories of these visits are those of learning to drive a tractor at the helm of Uncle Cecil’s 1948 Farmall Super A. Uncle Cecil was the second owner of this wonderful little tractor, but it was almost as though he had adopted an infant. The original owner was a man from Minnesota who bought her from a local dea
