Thanks Petak, that's them on their way from from meca parts, expensive but at least I'll have them if I decide or need to take this engine apart, just not sure which way to go since the engine has sat in a garage for nigh on 25 years.
The previous owner said it was an excellent engine when he took it out of the car all those years ago and advised me to just clean it up and run it,but I couldn't resist taking inlet and exhaust manifolds off for a look, when I did I found a fair bit of gunge and spiders! and a little rust on some of the valve stems.
I have cleaned all this through the ports but obviously can't get further in.
Quandry quandry !! I'm tempted to turn her over on the starter for a while with everything open, just have to make a decision !!
