tds;
If you don't already have one, I suggest you acquire a copy of 'How To Power Tune Rover V8 Engines by Des Hammill. It contains a ****load of info about these aluminum motors.
You can get it here:
https://www.aluminumv8.com/
If you call the # on the website I suspect that (Mark?) will be happy to answer specific questions about your project.
I don't see any reason that you would not be able to do the job as long as you don't hurry and are careful about what you are doing...and you pick a lot of people's brains...people who have experience with this type of job.
I told my tech guy that I was planning to remove the heads from my V8 and he said to leave them alone if you aren't having specific problems. Aluminum is a different animal than the cast iron we Triumph guys are used to. Torque values, tightening sequence and stud material are critical in fastening these heads and avoiding later [gasket] 'issues'.
Another thing I might mention. An E-bay store called 'Alloyboltz' will sell you the nicest set of stainless bolts for the Rover V8. Everything is bagged and labeled and packed professionally. I haven't used mine yet but it appears to include every external bolt that that the motor uses..except for the head bolts. The price was around $30 +shipping.
Keep 'on.
