Re: Head differences
So....
That was a lot of info..lol
Dan, what would be the reason for the ticking noise staying around with the same set of heads on 3 different engines? I helped a buddy swap an Aviator engine in his 1999 GT. He ran Crower 3's and made great power N/A. He then built it with 03/04 Cobra rods, Probe SRS Pistons, and cast crank....engine (cylinder head) still ticked.
He then tore the engine apart, rebuilt it, and had some work done to the heads, still retaining the stock guides....but installed +1 valves and had some minor port/chamber work done. The head still ticks to this day.
Every mod motor has piston slap? You are basically stating that every shortblock has this problem. I personally have had about 10 different mod motor set-ups and I have never heard one bit of "irregular" noise come from the engine. Several of thoe 10 engines were 4V's. And my current car is a 4V.
Thoughts/opinions?
