Hello,

I have a spare head sat in my wardrobe that I bought off Socks a long long time ago. I had it skimmed and vapor blasted straight away and it's been sat ever since.

It's always been my intention to build a special head for my Starlet, either renewed back to good as new, or maybe swapping out the exhaust valves to defeat the old school EGR, I read that on a UKSO page somewhere a long time ago.

Anyway, since I'll be putting new valves in it at some point, I figured it's best to get some new Valve guides.

So I bought some MRK valve guides, I was wondering whether anyone has any experience with these, whether they are an okay part to use.

To clarify, the car will never be designed to out live an OEM engine. I doubt it'll ever see past 30k miles in my ownership.
