Mike Reply: a gain of 30 HP is significant with no promises and I am looking at Carter and some tell me I should go with the new Edelbrock so far. I don't want to read through 600 posts again, just tell me if I need to port match the Intake to Heads, please, is that being Transparent?

Also, I read about Progressive Linkage and one other option would be convenchable or regular? What or how do they work?
