I am in the UK and am trying to source some new cylinder head bolts. They are impossible to get here. Does anyone on here know where I can get some from?
TIA

Why, they are not stretch bolts?
They are designed to stretch and return when the engine temp changes. That's the reason for what looks like heavy threads on the shank of the bolt. It's also why Honda recommends replacing them each time.

Not a word in the Honda manual about replacing the bolts. I worked on Honda cars for a lot of years and never replaced head bolts.

I don't have my 85 maual anymore, but I know when I blew a head gasket, my dealer recommended replacing the bolts. I did the work but bought the parts at the dealer. Maybe it was their policy.

So you have the head OFF and have it checked to be flat and going to use oem gaskets but before it was leaking coolant and now you are ready to put it back on and want new bolts but as mentioned above new aren mandatory for successful job.

He didn't do the work so he didn't really make any money other than the parts.
And made at least a 100% markup on those.

If i looked correctly,they appear to be 10x90 and 10x11.5 flange bolts.i would think a hardware store would have them in 10.9 hardness.

They are a very specialized bolt, not just any bolt will do. He still has not explained why he needs new bolts.
