| I just read Car Craft March 2004 issue. In the magazine, they did a story about roller cam. Well to make it short, on page 41, they used a 350 with roller cam, vortec heads with comps new beehive springs. It said they used "pure stock pair of iron vortec heads fitted with a set of Comp's new beehive valvespring." Hopefully I can get by with the beehive springs and not have to do any machine work on the heads other than to put screw in studs or pin the studs. |
