Not Ranked
As David points out : ... not that hard to do and not that expensive... I agree on that.
But, I'm still thinking how to upgrade my 8000(+) 347 this winter.
For reliability I was thinking going lighter on valve gear. So what's the deal? Titanium (or aluminium, if available and adviceable?) retainers & keepers is not too expensive and worth the money. Valves: Should I choose Titanium (1000$) or should I go for undercut race- valves like Manley Race Flo?
And here comes what I need to ask::::: while looking for the correct titianium valve, I cannot seem to grasp it... If a 11/32" valve is listed for a head, you should expect a 0,344" valve to be listed, but no! Only 0,3415".
Is this the explanation: 11/32" is the bore of the valve guide and valve stems are 0,3415" ? (Makes clearance 0,00225".)
