BEST FLOWING U-FLOW HEAD

Post by jovann46 »

My post relates to two questions:
1. What 8v u-flow head flows superior WITHOUT being modified/gaslowed out of the box(for 1600 carb - weber 38)? K-Jet was mentioned as well as ABC mp9 head(obviously with sandwich plate to cover F/I holes) as well as 2E/ADY.
2. Does the 2E/ADY head or the MP9 ABC head flow best?
3.Does the port and combustion chamber size of the mp9 ABC head(1600/1800) and the 2E/ADY differ in size?
4.When using d/ble valve springs on MP9/Crossflow heads what inner springs can be used? I have lost 2 ABC heads on single springs(300 deg hyd cam) and was told to go the double spring route. I ref 8200 on my race car.
5.My 026 103 373 F head(4 cap hyd - 288 estas) is still in one piece after 2 years but my ABC(5 cap hyd) lasted only 25 laps before dropping #3 exh valve,both is reved 8000 - 8200 and NO there is NOT coilbind

If this was discussed already please direct me to the relevant post.
