Wondering about this myself.

Yeah, so far I have only opened the port windows to match the gaskets. I have a LD4B and it was almost a perfect fit to the gasket before several minutes with a fine stone to fix the slight core shift. I only figured on working the roof of the exhaust ports and maybe the short side turn and...

I wasn't sure about removing the valve cover bolt bosses. I just ordered longer carbides so I will do that. I already got a set of ARP valve cover studs, so I won't have to worry about that part.

Here is what I have done so far on my 920s for my 273. I matched the intake and exhaust ports to my gaskets and smoothed the sharp edges of the spark plug bosses on one head. I plan on rolling the guide/roof of the ex. and smoothing the humps in the roof out the smoothing the whole port and bowl...

Bought the magazine when I saw it come out, interesting read.

From what I have read and found the Isky E4 grind is the closest solid cam to the factory 4bbl 273 cam. Lift is the same, but with a little more duration. Toolmanmike post about his Isky E4 in his 273.

So after playing around, if I put my finger over the top of the guide and pull out the valve at a good speed they make a pretty loud pop. I may not do anything to them right away now. I talked to a machine shop I have used in the past on the AL head in my daily driver and they said they don't do...

I recently bought a set of 920 heads for my 273. I have notice there to be more play with the valves in the guides then I feel comfortable with. I noticed some of the guides has rings in them, I assume knurling? I plan on doing gasket matching and some other work on the ports and bowls myself...

I am swapping in a set 920s myself on my 273. Just got them and boy are the ports going to need a gasket match to match my intake.

Mine are clearanced at the intake runners as well. I haven't got around to installing them yet though.

I found out the hard way about needing sealer on the header bolts as well. I had coolant running down the exhaust and though I had a cracked head at first.
