Crashing valves into pistons can be a very expensive mistake!!
Aggressive camshafts and high-compression ratios are conducive for maximum power in your engine, but they also create a very risky relationship between the valves and the pistons.
Alex Taylor shows you how to make sure this never happens to you!

well we forgot about squish. had a engine thats in my sons car. didnt have enough clearance between head and pistons. to correct it we had to run a .061 thick mls gasket to achieve .038. then on to the valve clearance. fly cut on the pistons to achieve .080 on the intake and .110 on the exhaust.

If the testing springs you are using are light enough it shouldn't be an issue. However if you want to remove all doubt, use a solid lifter to check the PtoV.

Yes! If you don’t have enough clearance. When the engine is spinning at high speed your valve me hit the top of the piston. This will most definitely ruin your engine performance🙁🙁

Good video, plus you're easy on the eyes, but the clay method isn't very accurate in addition to not knowing where the closest point was in relation to where the piston is. Piston to valve clearance should be checked during cam degreeing and checking proper push rod length while the degree wheel in still on the crank along with the test springs and dial indicator. There is also a way to use the actual valve springs to see how deflection affects the clearances.

Great point and when dealing with race applications this is the preferred way. However, not a lot of folks that are installing heads on a street car have these tools. If they do, they most likely already know how to check all the necessary clearances.
