454 Plugs

What is the correct plug for a 454? It seems that they have to have a long thread.

I believe those to be correct for 71' and 72'.

I thought the long reach plugs were R44XLS or R45XLS plugs ????
Not 100% sure here. The long reach plugs were used on pre 70' BB I think and aluminum heads too.

I could be wrong here though ...

That's exactly the plug I need for my '71 LS-6. If you ever run into any I would really appreciate it. Thanks, Warren

Looking for R44XLS

I really like Accel #276. If you have a clearance problem with the headers #276S is about 3/8th of an inch shorter.
The only reason I changed my accel plugs that I have been running for years is that I got a free set.
