ATX, you need to be a bit more concise with your topic subject when you start a thread if you really want guys to answer the question. Using titles like "Help" or "question won't get you far. I am editing these so you can get an answer or 3, please do this in the future. Thanks, Dan

Wait, a R43T is a 14mm 5/8" reach tapered plug. Many SBC aluminum heads take a 14mm 3/4" reach gasket plug. Like AFR and Procomp. If you use the wrong one you may end up with the plug being shrouded in the hole.

OP, we need to know what brand of heads you have.
