I was putting my headers back in and stripped a header bolt thread on the #5.

I have a heli-coil kit.
But its pretty tight to drill the hole 1st with the 25/64 drill bit.
I bought an angle drill but I'll have to cut the drill bit shorter , and even then it may not fit.

Any other pointers to do this while the heads are still on the engine and in the car?

You're on the right track, as long as the drill you have will fit into the space at hand.

 

It's not looking good.
There's just not alot of room in there.

Might have to bite the bullet and remove the head

 

Do you have an air ratchet? They make a 3/8" drill chuck that will fit on a 3/8" ratchet drive. That would give you a much smaller right angle drill.

 

I could get an air rachet.
Can you show me a pic of what you are talking about?

 

I have used this and it does the job well just expensive

 

Here you go man. http://www.cowanchuck.com/

I bought an off brand china one from jc whitney about 12 years ago for like 10 bucks

 

I got it!

I originally bought this drill

But the trigger is on the wrong side!

So I bought another one with the trigger on the inside

Just barely enough room for it to drill, but I had to cut the drill bit down.

Then installed the heli-coil

Woohoo! Headers are back on
