I'm pretty sure the Renix head will bolt up to the 95 block and then all of the stock Renix stuff will bolt up.
The only thing I would be concerned with would be the knock sensor. Not sure is the 91+ blocks had the bung to mount the sensor to.
Have you considered having your engine rebuilt? Granted the price will be more, but this way you'd have a new engine and not a second one with miles on it.
Depending on your budget, www.quadratec.com
sells new long blocks for around $1600 with free shipping.
