sounds like a 216 intake. studs should be 2 15/16 for the 235 and 2 11/16 for the 216. if you can find a part # cast on the intake post it and someone may be able to give you a positive id. you can also go to http://chevy.oldcarmanualproject.com/ and find references to the part # yourself. good luck
