I have Edel. aluminum heads on top of my iron block as well. I have the same "K" cam that was spec'd for the original 427-8v low riser engine when it first came out, and that was subsequently available upon request as a service item when the medium-riser was made available. Duration is 245/245 at .050 with a lift of .525 -- The LSA is 114 degrees and I have it installed 5 degrees advanced at 109. The original Ford spec's called for .024 lash HOT, and I set my lash at .018 COLD. My setup has the lash grow by almost .006 when it goes from cold to hot. This is an "old school" throw-back cam, and I love it. Blykins enjoys making fun of it though.

yes i think it's a little too tight. set them when the engine is hot. at .024

how much they will grow from cold to hot will vary.....you have enough unknowns at this point. too tight could bend a pushrod or bust a rocker or worse....

I don't know how anybody adjusts valves hot. It takes me all day to do my valves -- and I usually split it up over a weekend.

With a remote starter, should only take 4-5 minutes at the most. Lash is given as a hot spec, how do you know what they are if you don't set them hot?

I check them hot after I've set them cold, and they're very consistent -- they all grow by just a little over .005 -- I just can't set them that fast so they wouldn't cool off. When I do it, I turn the crank over by hand, look at them, pick up the feeler gauge, drop the gauge, look around for my little T-Handle adjuster thingee, adjust one, tighten the lock nut, re-check, re-adjust, tighten, get it just right, sit down, rest, turn the crank over to the next one, rest, get a snack, play with Ellie, check Club Cobra, do another valve, re-check it, find that tightening the lock nut threw off the lash, re-do, rest, check email, post something to annoy Chas, go back to the valves. Since I forgot where I left off I re-do one, since it's not quite perfect.... And so on, and so on.... Seriously, it takes me all day.

heheheh, and is this the pace you go with when litigating....and charge by the hour....
or do you ramp it up for that?
it is quite honorable you include Chas in your busy schedule though.
