I've got a new rebuild 360 Mag .030 over with 40+ miles.
Edelbrock stock heads. Comp cam 220 276 290 .547 .544.
Push rods were measured before hand and got Crower 6.950.
Speedmaster 1.6 roller rockers
Broke a stud a few days ago while driving under 2k RPMS #2 intake. Replaced and drove it easy for about 38 miles.
Today I broke #5 intake after start up and idled up at 1500Rpms.
Are the rockers walking off? If that's a thing or any suggestions?
