if a head is milled, do you set TDC with the cam at 0 Degree setting or at the advanced Degree setting? here's a pic to explain what i'm asking.

 

common tech gurus!

 

i would think at 0 degrees. but i am a little confused by what you're asking. did you just mill the deck? if so then i would say 0 but that's my opinion

 

for every 1mm you mill is about 1.14 degrees the cams get retarded.

 

ok guys thanks for you input but thats not what i'm asking. I understand that the cam must be advanced so so 1 degree for ever 1mm blah blah. but the question i'm asking is:

at which configuration should you use to set TDC?

 

heres a better pic of what i'm asking.. this should be more clear.

If you rhead is MILLED, do you set TDC with the INNER or OUTER marks of the CAM GEAR??

Loosen your cam gear adjustment bolts, set the crank pulley to TDC on #1 (make sure the distributor rotor is pointing at #1 as well), and tighten your cam gear bolts. Your cams have now been ghetto degreed to zero.

 

the proper way is to use a degree wheel and set tdc.

 

Hence the term "ghetto degreed".

 

find how much what the lift must be at TDC from honda then dial them in

Holy labor intensive. Not to mention, how many people have three dial bore gauges hanging out in the garage? I don't even have one yet...yet.

 

No, I don't agree. With the crank at TDC, you want the cam right on the mark.

Problem is, after you've milled the head, you'll find that you need to position the camshaft sprocket at some fraction of a tooth.

Its like your third picture. The sprocket can't be positioned perfectly because it would have to be in-between 2 belt teeth. So you have to compensate using the adjustable sprocket, to put the actual camSHAFT in the proper position.

 

^^ Which is what my "ghetto" method does. Well, in theory anyway.

I should add that if I had three dial bore gauges, I'd more likely than not use the method from the link.
