It will never be as good as a non-sleeved block. Cost a fortune to fix and still a marginal foundation for a once great engine. If you have a virgin-un-cut head, I would use it and install shallow seats. JMO.

Sort of off the OPs topic, but on a Pontiac, you know, the cool engines, how many sleeves in a block is acceptable before it becomes a negative ?
I have a couple of 400 blocks that might need a sleeve or two.
