Does anyone know....

if there are any places that make pistons for a 170 with valve reliefs? Or any pistons for a 3.50" bore that have valve reliefs that would work with a 170?OR lol anyone know some rough estimate prices on a set of custom pistons?

Something like this would be great

i think that Isky cams makes a tool that you can use to cut reliefs into the top of the piston, prolly worlds cheaper than custom pistons

Ok, I´ll ask.... why do you need/want valve reliefs?

thinking about a blown,direct port nitrous injected 170.If I go that way I'll need to hop up the cam and I really don't want my valves and pistons getting in a shoving contest.That and I'm not too sure I want to use stock pistons with nitrous.
