engine quest E/Q cylinder heads

flow bench says EQ has a bit better flow OOTB although most edelbrock lovers will argue that point. Seat of the pants dyno, I think the EQ feel stronger but that might be me. If you bolt on a set of EQ heads you should see 400+ hp from that short block/cam combo.

Pretty straight forward as far as engine builds go and a good base line to start with to decide if you need more than 400 hp.

With bare sets under $800 shipped and complete w/larger springs for that cam at under $1150 shipped, they are a pretty good deal. All our customers that have them have absolutely loved them.
