Ok after waiting a year porting and flowing my Stealth Heads! I thought I was ready to bolt them on. FOLLOWING the directions in the box from 440 Source, buying correct gaskets, changing to 928 springs and 10 degree retainers, following the prescribed #torque. I was ready to set the valve lash. It was fine until setting the Intakes there wasn't enough clearance for the 3/8 pushrod. Now what? Call 440 Source and the answer is!!!! Oh didn't anyone tell you when you bought them you have to clearance the intakes??????? NO NO and NO. Not on the install sheet, not in the add and certainly not when I order. Advertisement read great heads bolt on the power. THANKS 440 Source!!!!!!!!!! Is there anything else I need to know before I fire and make a run down the track??????
