Any of you guys have any input?? I am looking to throw a set of the AFR's on my boat with twin SBC's and I am wondering if I should run the angled or straight plug.

I am thinking the angled plug will give way mor clearence to the manifolds, as the factory heads have staright plugs and it is close!!

Thanks.

so it is going to be in the 492-ish range? i was going to ask...why does noone use oval ports? they go straight from round ports to rectangles. from what i hear, the square port doesn't even start to flow until 6000 or so.

I was thinking maybe this was a very heavy slow boat and thats why they are stuck on oval ports, but that is not the case. I run Brodix BB3 EXTRA-0 331cc oval ports on my motors but they are much larger than the std oval port type heads. I think any of the Dart, Brodix, AFR etc small rectangular port heads would also be a good choice.
