I AM THINKING ABOUT MOVING UP A CLASS
TO THE STREET STOCKS NEXT YEAR AND WAS
WONDERING WHAT CASTING NUMBER ON HEADS
TO START LOOKING FOR. I DONT THINK MY
PURE STOCK HEADS WILL CUT IT IN THAT
CLASS.

Depending on the street stock rules at your track, there are several OEM casting numbers that are good. My favorite genuine chevy set of heads for the small block is the 292's, which have angled plugs, blocked off heat riser passages, and 2.02/1.60 valves. If they don't allow them you might want to look for 041's, 186's, 291's, 461's, 462's, 370's, 414's, or 492's. A few of these came with either 1.94/1.50 or 2.02/1.60 valves. Some also had an "x" behind the part number which usually meant about 10cc more intake volume. There are other heads that I'm not mentioning. There is a smallblock head part number identification guide in the toolbox here on the forum you can look in or possibly go to Mortec.com for more information. If your rules and your budget will allow it, the aftermarket "World" heads with straight or angled plugs and 2.02/1.60 valves are a great set of heads for the buck. Good luck in the new class!!

Definately need to post the motor rules to give a definite answer. Is their a claim or Imca rules. If you are limitied to cast oem heads I would say vortecs or bowties, If it is open I have heard good things about Dart heads. Camel hump heads are the most popular choice around here because of our rules.
