Cylinder Head Porting - Post Pictures Here

Stupid noob question. Could you use something like JB Weld to achive the same results?

Thats a good question.

Well JB Weld can withstand 500 F continuously or 600 F for 10 minutes.

The cylinder heads get to be about 400 F at the spark plug.

I THINK Exhaust gasses reach something crazy like 1100 F or 1200 F.
I might be wrong.

I wouldn't trust it. But I'd like to know.

LOL, that sounds suspiciously like, "Why don't you try it and let everyone know how it works out!

Although, since I suddenly have a plethora of motors, I might choose one to be a "test subject".
