Looking for a little more power out of the motor. I currently have 461's w/1.94 1.5 valves. I run flat tops w/ an isky 465 lift cam and a 750 holley on top with a Victor jr intake. Please let me know what ya think a good set of heads would be on this motor. I was looking at Dart 49 cc (bad castings?) or the Pro action 50cc. Thanks, Race I run a small 3/8 dirt track in a 3300 lbs metric.

either of those, dart/pro action are good heads, particularly if you have to run steel heads. if your rules allow you to run aluminum heads, then there are plenty on the market depending upon your rules.
if you have to run steel heads but there is no valve angle rule, pro action (iron lightening) make a 14 degree steel head very similar to there aluminum sprintcar style head.

Pro actions were getting tough to find recently (new at least), so I got a set of the Dart Iron Eagle's - they bring the compression right up with a flat top engine and so far it seems to have good power (now to work on the handling!)
