lol I meant combustion chambers where bigger. Was in a hurry. I think you're the first to catch ekacpuc in the 10 or so years I've used it. Thise whole bbc thing is throwing me through loop after loop. Turns out its a 454 .60 over GEN V. I hear mixed things about edelbrock.
Better way to ask my question is its about the same price to change to .200 dome pistons and use the dart heads as it is to keep the flat tops and go with the performer head. So what I want to know is with the performer heads and a 9:1 CR and something like a comp magnum 280 cam can I hit 500hp or get close or am I better off going with the bigger intake runner and high domed pistons to try and get 500 hp?
