273 correct heads?

Can you give me a reply to porting heads/intake?

I have a 69 273. Wanting to do Edelbrock MPI fuel injection. Edelbrock says it will only fit 340/360 heads. Are the intake runners different on the 340/360 than the 273/318? I am contemplating using the 234 head, and having harden seats installed.

"Start a Conversation" with Justin. He is in CA, so he is 3 hours behind us. 273/318 intake ports are smaller than 340/360 heads. Skip the hard seats until you need them.
