Should I block the exhaust crossover on a street engine?

I was getting ready to install the edelbrock performer intake on my 455 ('72 block, '68 pistons, 9.4:1 compression, stock heads (GA), 1 3/4 headers). I was reading the instructions, and they said to use the included exhaust crossover plugs for competition and marine appliations. Should I use them for a street engine? Thanks. Tom.

NO! Too much trouble on a street engine..I have seen those plugs work loose and rattle as well...And you live in a COLD climate...not worth the time
