Disaster strikes solid roller, possibly wiped out cam..
We've been excited to get the car to the track and with the final build parts coming monday it looked like we could hit the track Friday. Last night we fired up the car with the new exhaust and dialed in the vacuum system. I had noticed more valve train noise than normal but I thought it was normal for a solid roller. I pulled the passenger side valve covers and adjusted the lash, it was very very close maybe .02 out and left the driver side for the next day. I pulled the driver side valve cover and all looked fine. I lashed 1 3 5(exhaust and intake) and 7s intake. I rolled the motor over to check #7 exhaust and something didn't look right. There was definitely too much play in the valvetrain. Tried adjusting the adjuster and it wouldn't take the lash out.
Pulled the rockers and the pushrod was straight but the lifter end had some wear. At this point I am assuming that either the lifter is damaged or the cam lobe is gone. Either way its not going to be pretty.

You sure you got the right valve springs? Solid rollers take a pretty hefty spring as i use to use them in my 67 chevelle 572 bigblock. Have had a few lifter failiers becasue of valve spring problems. Also check the geometry of the valvetrain might not be right on spec.. Easy to do by marking the tops of the valve with a black marker and turn it over and see where the roller tip of the rocker if it is centerd or not..
