Magnum heads on a 74' 318 LA

Still running that LA with magnum heads? I've had a shop build a 73 360LA with Edelbrock magnum heads, and I have all kinds of problems with the lifters. Curious about the work you had done to the block ... can you be more specific?
Thanks - tried to send a private message, mailbox was full.
Yes, I just had the car out today. Sorry about the mail box, my wife passed away a while ago and I haven't been on here much. Question, what was the problem you had with the lifters??? I used a roller cam from Bullet and it works fine for me. I did go to adjustable roller rockers to get the correct lash. I used a dual plane magnum I got here, the combo works good. Next step is FI!
