I've had that inlet manifold off a zillion times in the 31 years/over 300,000 kms I have had my car. I have never had a problem with those front water passges. The have little flow, they are only a "highest point" air bleed. All the real flow is through the rear water passage. Rather than just clean the threads in the head, bite the bullet and fit heli coils. Obviously be very careful re depth. I did mine first year I had it, never regret it, it makes it so much easier, and you'll never have that "last bolt turns too easily/stripped". Like the bloke who invented the rear view mirror. Since that day, he has never looked back. :-)

Run the brush in the threads to unscrew the thread, u just push the dirt down in the hole
i would have replaced the water pump ( or at least a refurbish with the impellor machined flat ).
Good job well done, Hope all goes well now. Bob
Well done mate 😊
Did u upgrade the water pump? Lots of engines ruined because of lack of circulation
you can't beat Trevor and the team at Faversham Classics
U have beautifully polished valve covers !!!! And utterly rusty bolts I wouldn't even deign to b thrown in the bin...
Good job.
