Edelbrock RPMs vs Indy SRs

[mastrdrver]

I am building up a 451 in a Dart and was wondering if anyone thought if the SRs would fit in a Dart? I think I would rather have the SRs bcuz they flow better and would be able to get more out of them with the same sized cam. Also does the 6-pack intake work with the SRs? I was planning on using one. How is the 6pack on milage compared to a single 4barrel?

Thanks

Installing SR heads on a low deck block, puts the exaust ports very close to a RB motor with stock heads.

Yes a stock 6Bbl intake will fit SR heads, as long as you stay with the stock size intake ports.

There is a story in Mopar Muscle on these heads. According to them its not all what they say. They had to buy the Inday manifold as the RPM would not fit. Pushrods , their valley pan, an external oil line to each head. Get it read it.
