Upon doing some further reading I came upon something I didn’t realize. The edelbrock aluminum performer rpm heads which I’m swithcing to from my 915 cast iron heads have angled spark plugs. It says that the plugs are angled 15% towards the exhaust valve. I’m wondering if that is going to be a problem with my Schumacher tri-y headers going on? Well I guess I’ll find out soon enough. To answer a previous question in this post. Yes I already bought the heads and had them gone over for any inconsistencies and corrected by a local machine shop I trust.
