stock computer? any timing/fuel controllers at all? RRFPR, ignition retard, nothing?
theres your problem right there. youre just running way lean in boost and detonating like crazy. i bet your ring lands look like shit.
get yourself a RRFPR or better yet TCD's turbo ecu. he has a generic off the shelf 413 ecu (though with your car which is a 403 off the top of my head) im not sure if he makes one for that one.
fix all your headaches right there. stock block m50's can handle 18+psi/600+rwhp with good tuning and head studs. ive seen it done and last 10k+ miles.
