roller lifters. cradle versus tie bar

G'day

I'm loving this website. Heaps of great info and helpful people.

I'm plannin a 355 build. I've got a complete vt block which had been removed from a car fire. It melted the engine covers and licked the intake but the heads still have the paper gmh stickers on them so I don't think they and the block got hot.

I bought the block because I believe they're stronger and I like the idea of a roller cam.

After reading how another member recently had his cradle break and allow the lifter to turn I'm wondering whether I should get the tie bar lifters or stick with the origin spider retaining plate (I've got 3)

Any advice or relevant experience??
