Thermostat
 

I moved this over from Q&A

I changed my old log style exhaust manifolds to center rise. My old manifolds used 3 cooling lines each center rise use 2 each. Thermostat lower has 4 outlets upper has 2 outlets. Does someone make a cover/ block off plate to get rid of the upper? I'm working on a 79' Scarab 300 with twin 330 BBC and TRS. Thanks for any help
