I just purchased replacement head bolts from ARP for my 261 and they should also work for your 235. The 5" bolts are longer than the original 4-9/16", but I measured the head and block and the longer bolts will work with room to spare, even with out the added washer and head gasket thickness. If you do decide to order them you should measure to make sure these bolts will work for you (make sure the bolt holes are clean). If your head and block have been milled your clearances may be different than mine. Here are the ARP part numbers:
6AR5.000-1.....1/2-13 12PT Bolt X 5.00" $8.99/ea
6AR3.250-1L.....1/2-13 12PT Low Head Bolt $4.70/ea
ARW78.....Chamfer Washer 1/2" ID, 7/8" OD $0.69/ea
Good luck.
