V8 273 head question

Romulo Roderiques said
Which Edelbrock do you recommend? I have a 2176 and the middle runners weren't even close to matching on my 273

Are you talking about the heat crossover in the middle? 2176 should work. I have used 273 intakes on 318's and 318 aftermarket intakes on 273's. Never a problem. Do you have to use a 1/2 inch wrench on the 273 intake bolts?
