What headers for s.b stroker in Early-A

I want bigger headers for any hot performance small block. I have the TTI's and they perform great on my 69 340 4 speed, but the engine is capable of moving more exhaust if it had the room. I spent a lot on them and the coating did not hold up. they were also supposed to be a bolt in and they were supposed to be installed with the engine bolted in.....no.

I had to adjust the crap out of the pushrod at the z bar and i cut my pedal pushrod in half and welded a piece of pipe over it to lengthen it. It was the only way I could use my clutch! I kinda need the clutch so I did the mod but the z bar pushrod is way beyond compfy adjustment...not a good angle. Of course TTI had no clue why this would happen.....
They said they would slide in from below without pulling the engine...so i tried it...I even lifted my whole front end with my engine hoist so i had 4' to play with!!! Nope...not hapnin! LOL After dismantling and reassembling my front end...I lifted the engine and finished my ALL weekend header install....nice!

These are the ones I got...but it was a while back, i got them direct from TTI.

P.S. and I agree with Rumble...any hot smallblock...400+ HP...needs bigger headers to achieve full potential.
