I can’t figure out why none of the aluminum head manufacturers won’t put Helicoils or TimeSerts in locations where steel bolts are going to be threaded in and torque applied. The combination of steel bolts and aluminum threads triggers galvanic corrosion.

Edelbrock exhaust bolt holes are helicoiled, but they are the only holes to receive the coils.

If you check my long-running thread you will see that I recently discovered that on my 87cc round port heads the rocker stud threads are also coiled.

Sorry to hijack the thread. This weekend whilst at the race track, I was re jetting my carb and stripped a thread for the float bowl to carb body. Its a holley 800 double pumper. Presumably I can helicoil this? What thread size is it?

#12-24 which is a standard UNC thread.

Its very important to pay attention to thread engagement into aluminum as well
i usually bottom tap blind holes and use a bolt that catches maximum threads, sometimes start out with a long bolt and trim it down using a thinner washer under the bolt head trim the bolt until it clamps then put thicker washer under the bolt head

Aluminum threads are why I've always worried about using a carb plate on an intake to lift a motor!

Got the 3/8 kit from auto zone ,had to buy the 25/64 bit from lowes fixed in under an hour double checked depth of hole.Tightening it down felt much more secure.I was going the time cert if it was a helicoil that got pulled out.Glad I didn't have to I've heard the time certs are much more weaker
