Well I am not an expert match maker however I went with the Fenton set on my 235. I am sure you will get many opinions here but you can try here
Clifford Performance. I do not have any experience with Clifford but seen some at car shows on the 235.
I personally would make a call to Tom Langdon at
Stovebolt Engine Co. and Patrick Sr. at
Patricks and see what they say. Everytime I have talked to them I have received very good options and information.
