I actually did miss something when I read "Cam regrinding explained" and it was the whole reason for my post.
"you have to adjust
the rockers to now reach lower"
Don't know how I missed that part of the explanation.
Somehow my brain registered -By removing material at the base of the cam lobe, you have adjusted to rockers to reach lower and increased the valve travel into the cylinder.
My whole post referred to not adjusting the rocker reach, which wasn't what the explanation said.
Sorry about that.
I had a cam all boxed up and ready to ship to crower cams, with a cross section of head with valves and cam caps and rockers, Larken and I chopped up for porting research. The owner wanted it for grinding research, we talked a couple times on the phone, when he told me about the HLA washers and valve cover tap I cancelled that idea.
The way I see it is a professional company that knows what they are doing covers all the bases, even for a car with solid lash adjusters any cam regrind should fit the functioning engine or made to. Sell a valve cover spacer and HLA shims with the grind or a custom valve cover even. The idea of trying to find the right size washers in a hardware store or to shave down the baffle plate support evenly (and it's effect on oil/air in the baffle), or run without it and burn lots of oil or make a custom plate
or put a ford probe part on a Mazda engine made me feel it wasn't meant for these cars.
I looked into colt or comp cams system of adding material to the top of the lobe, to increase lift without changing rocker dimension or effecting valve cover clearance. But at 25$US per lobe and then the grinding fee I found it to expensive.
Was always curious about the cam regrinds performance on an F2T putting out decent power, I don't recall anything but stock IHI dyno's with custom cams. On this forum.
It usually seems to be the bone stock internal engine guys making high power and the 3angle valve job, custom cam, high compression pistons, forged rods, decked head... guys running more conservative sized turbo's or boost, possibly to protect their investment . (Ademan excluded)
Or a really expensive engine build and lots of forum activity, then they just disappear, I figure they blow the engine in the first few days due to lack of tuning and don't want anyone to know.
