Okay, let's address this as two problems: overheating and detonation.

Overheating:
replace the radiator cap with a 15 pound Stant lever cap. Replace the t-stat with a Ford OEM 192 degree t-stat. DO NOT buy an aftermarket t-stat. Buy it from Ford. Flush your cooling system. Buy a puke tank. The cooling system relies on having an overflow tank (puke tank). The heated coolant expands, and surges into the tank when hot. When the engine cools, it siphons the coolant back into the radiator. If there is no tank, you will eventually start to regularly run low on coolant. Install a coolant/water mixture with a ratio of NO MORE than 25% coolant/75% water. More coolant is not necessary, and will make the engine run hotter.

Detonation:
get your engine as close as you can to TDC. remove the #1 spark plug, and insert a pencil into the spark plug hole. With a breaker bar attached to the crank bolt, rock the engine back and forth, watching the pencil, until the pencil reaches a point where it no longer moves up or down. This is true TDC. Mark your balancer right at the pointer. Measure 15mm to the right of your new TDC mark on the balancer, and make another mark. This is 10 degrees BTDC. Now check your timing, and adjust accordingly. This, combined with a good cooling system, should solve your problem.

Take care
