What are tuliped valves??? What does it take to turn a normal valve into one???
Long story short, engine shop
srewed me, They claimed that because I had the timing set at 16 degrees base for the first 350 miles (they reset it to 12 which worked for the last 4500 miles) that that caused the valves to overheat. The head is not warped (made by future head designs, stock 782 head with stock cam, head heat button did not pop, no discoloration on the valves or the head at all). Engine has been bored .30 over and still has the honing marks pistons look great, stock injectors, T2 garret 465133 2x model, computer by fwdperformance stage 3, stock ignition, 2.5in exhaust to a spintech muffler (no CAT), no bov. Engine lost compression at 5500 miles
. Cylinder compression test as follows
Appreciate any pictures of tuliped valves and ways you can tell or measure if they are. Also any insight into redoing this motor would be great (this time I'm doin it myself and it will be the first time for an engine over 1 cylinder)
