    I’m confused here..  So someone is trying to replace a pre 59 5.5hp block (no thermostat), with a 59 or later block with a thermostat?  If so, this isn’t gonna work for a few more reasons.  Nonetheless, the older exhaust cover will surely not fit on the 59 and later powerhead, but it seems that you know this already so I’m not sure I understand what you are asking about….
