I Thought I'd reserrect this old thread.
I just got an email from a perspective customer asking what had to be done to put a K top end on a WL bottom.
At the risk of potentially exposing myself to the mercy of the many knowledgeable members of this forum, I will ask for any comments, suggestions, or whatever, by posting my response here.
"What you need to complete your project are my angled WR tappet guides , these are designed to be used with standard WL roller tappets.
My WR angled cam lobes (available in various grinds) which need to be timed and welded to your existing WL gear clusters (the ones with the push out shafts).
WR valve covers which I do not have in production yet. The standard covers will not work because of the large threads.
I don't think the sportster cams will work, they have even less lift than the WL cams because they make it up in the rocker ratio, also they are designed for OHV motors not flatheads..
If you use my hotter cam profiles you should replace the valve springs, Steve Hartley has these available.
All of my parts are direct bolt in except for fitting the cam lobes.
On the KR cylinders the bolt hole near the exhaust lifter is NOT in the same position as on the WL or WR. You must either move the stud or the hole (may be easier).
You will also need a K or WR intake manifold and I think K pipes will work but I'm not sure how they will clear the bottom of the timming cover. "
What is this forum's opinion as to the correctness of this response, any additions, deletions, or clarifactions.
Please be gentle!
