Wenzler Gutsram to factory iron heads
I just bolted up the Gutsram to an iron head - or should I say I tried to! The outer bolt holes on the Gutsram have nowhere to thread into on the iron heads, there are voids where the bolts should go. From what I had read about this manifold it seemed that I would have to drill a couple of holes in the heads at the outer locations, however I'm assuming now that this would only apply to aftermarket ali heads. So, it looks like I'll either be welding some extension pieces on the ends of the manifold flanges, or welding receivers into the heads to take the bolts.
Unless someone has already been this route and has a better idea? Don't mention ali heads - they are not what I want at this time....
