wrong plugs

bought a 95 camaro...found out too late that it has a 93 lt1 put in last year. I put 95 plugs in it that have the same gap (according to oriely's guy). They said the threading is different....is this going to be a problem or will it damage the engine?

I thought all gen 2 lt1's used the same spark plugs. I always put anti-seize on my plug threads, but again if they went in without effort, the threads will be fine.

I meant length of threading on spark plug is different I guess because the plugs go in at an slight angle on my engine (93). My concern is that that may be too close or far from cylinder. But I really don't know what im talking about so I'm asking ya'll

Like stated, ALL lt1s with stock casting heads have the same threads. They ALL go in at a slight angle. Every lt1 made from 92-97 uses the same plugs

tell us the number of the plugs that were in it

if they are too short on the threaded portion, you get combustion products or heat up the bottom portion of the threads. then when you try to put the correct plugs in later, they barely want to thread in.

if the thread reach is too long, you could smack a piston, but they'd have to be pretty long (like the NGK plugs that start with L)
