We have the engine from my '87 TR torn down. Took the heads to a machinist and he magnafluxed them for me. Said the area around the valve seats is cracked on cylinders in both heads. Claims he can install inserts. I've heard bad things about inserts on boosted cars (like they come off and destroy pistons/cylinders/valves etc.). So, several questions:
1. Has anyone even heard of cracked valve seats? I never had before.
2. Are inserts bad or is that just rumor?
3. Are the turbo engine heads basically just stock '86-'87 3.8 heads? If not,
4. What heads interchange? How about hot air ('84-85) heads?
5. What's an 8445 head?
