triple springed? can't say ive ever heard of that, but...

i'd say pop a valve cover off and watch what is going on when you spin it.

pull a head and look for damage to the pistons or valves.
rule it out.

maybe even invest in a telescoping microscopic camera. they're gettin cheaper, and come in handy more than once.

if the block has been milled and/or the heads shaved, the pistons may still hit the valves. Also may depend on duration. Also what if the cam was ground wrong with some funky firing order that wont match a ford crank????
