I'm not even going to try to have this fixed.
I found a good deal on some Trickflow 240's I'll be picking up this weekend.

Stuff like this keeps me in 906s in my car. I just drive and drive and drive. Aluminum would be nice, but would be a constant worry as to what’s happening in there.
I want my fair share

The seats in our 440-1 heads failed likely due to weak valve springs and/or a weak hydraulic roller lifter. My engine builder thinks the valve bounced on the seat and hammered it right out. It was a bummer because we were about to rebuild the engine after that weekend anyway. I had plans on pulling it apart and doing a wellness check this Winter. I did the transmission last year. My eventual plan was a set of Trickfows, I just got forced into it a bit early!
