    Here`s a clip of the dyno sheet from Edelbrock for there Performer RPM kit. I used 64cc heads instead of the 70cc heads they used and can still get 98 octane gas without to much problem over here in the UK. I thought this was a better option rather than choose a lot of parts that might not match up with one another.

    FYI another option which produces a better combustion chamber quench is using the 70cc heads and milling the block to 9".
