are regular helicoil inserts ok for the intake-to-head bolt holes on the heads?

I've seen the regular coil inserts from helicoil, but i've also seen another type which are for heavy duty things like spark plugs holes.

Any recomendations?

PS this is not for my sc, but for a 5.0 motor im building...but I am using aluminum heads.

any help appreciated.

Thanks!
 
I would say they would be fine. Can you not re-tap the hole? perhaps somthing a hair bigger? i think they are 5/16 threads..
 
i would retap if you could, but otherwise you should be fine. if you ever have to take it off keep in mind most times they break loose before the bolt is out usually resulting in drilling the bolt out.
 
I have used helicoils on intake bolt holes, and worked fine for me. I always lock-tite them as I run them in.

Yeah, i read about using locktite on them



Thanks for the input everyone!

tho i would think if you locktite them in the locktite is gonna make it hard to get the bolt out because the locktite will seep thru the helicoil.. i could be wrong i never done it.:eek:
