All this discussion about the use of siamese blocks on the street has me concerned, since I'm planning on building a 557 cubic inch big block Ford using their SVO Sportmans Block (M-6010-A460). I will be using a Lunati stroker kit with about 11:1 compression, and a Crane Cams mechanical roller cam (.718/.718 lift, 284/294 duration). For heads I'm going to use either Blue Thunder, or the Ford SVO aluminum heads (M-6049-C460) designed expressly for the A460 block.
Will I be risking a blown head gasket since I'm going to drive this car on the street as well as the track?
You advice and helpful hints is readily appreciated.
