Ok...just checked valve clearances on my 88 n/a tonight. They were almost all out quite a bit. The car runs very well, but the top end was noisy and ticking quite a bit. All but a couple on the intake side had at least .5mm too much clearance. Almost all the exhaust were at least .5 too tight. This is my first go at this does this seem typical for a well used engine? The prev owner did a HG 20-30k ago but I dont know what he did to the head. I've been using JSeaman's guide , its excellent!

Too tight seems a bit odd for a old engine, but maybe the PO changed them. Pretty straight forward, just make sure the engine is cold.
thanks for the replies, I will double check them while I wait on a tool to come in. I thought is was odd also, but about half of the exhaust side I couldnt even get a .1 mm guage through and had to go smaller.

Tight seems to be correct in my opinion...
Overtime the valve wears, valve seat wears, valves stretch...
