Valve float doesn't necessarilly result in piston to valve contact. Actually, it rarely does. Valve float is simply lift(and everything it encompasses- ramp design, etc.) outrunning, if you will, spring tension and most production engines will eventually experience it at one time or another...
I'm afraid I don't see anything at Electrosil's website regarding information the thread-starter is/was interested in- thermal conductivity, coefficient of thermal expansion, etc. of (generic?)Nikasil coatings/linings. Personally, I find what information is listed at that particular company's...
Here, I just ran across a link I had stored explaining a lot regarding TBI on 305cid sbCs(not quite your engine but the basics remain valid):

The heads I have are World's Sportsman IIs which feature tapped ancillary holes on both the front and rear faces of the heads. Luckily this allows me to use the rear of the head as an attachment point rather than having to work around the power steering unit located at the front. After...
Is the consensus now that I should use components rated at around 2500-3000 lbs.(4-7x engine torque)? I have a limited amount of room to work with(about 8 inches- the distance from the cylinder head to the frame) and when I looked at turnbuckles and related parts at Home Depot I was disappointed...
One of the most important areas of concern in a typical stroked 383 sbC is the camshaft. Most builders will choose a 6" rod which, due to improving dwell to an extent and optimizing the quench area(typically dished pistons are used with 6" rods), makes correct timing of exhaust gas evacuation...
While maybe not the exact answer you're looking for I've always read that a good safe(note I don't say optimum) oil pressure rate(which surely relates to your "flow rate") for V8 automobile engines(namely the smallblock Chevy) is 10 pounds of pressure for every 1K engine rpm.
I have a 360cid smallblock Chevy making approximately 400 lb. ft. of flywheel torque in an '84 C-10 1/2-ton pickup. I plan to add a torque strap consisting of grade-8 bolts(to the frame and cylinder head), small sections of chain and a turnbuckle. My question is this- how do I go about...
