Yeah, I kinda was thinking it would loose torque & HP,but @ least you tried it.
I had the best luck w/ Carter AFB 400 & 500 AFB's,I even used a couple Carter AVS 625's,but it seemed a bit too much & could not get the secondaries to come in at just the right time.
When you get the side drafts on & working good,the torque increase should be a big amount.
Any guess on how much HP loss w/the cast iron headers?
I am guessing not too much if any by this engine build,but hey, I could be wrong.
