Diy Valve job

I think it's great you want to try. I've been doing my own heads for years - some of it. I've had years of service from these heads. Some of these heads are still on cars out there after 20 years. I'll list what I do at home with common tools...

• Disassembly
• check guides and inspect heads.
• Lapping the valves & check for leaks
• porting
• install new springs, valves if needed & valve seals
• assembly

What I can't do:

• install new seats or new guides. However, I'm sure it can be done with some "DIY" tools intended for that purpose.
• magnaflex for cracks. But, I can look closely for cracks in common places.
