Quote: Are You CERTAIN these are 2.14 1.88?Those combos CANT work in stock location.Max Wedge were 2.08 1.88....The 1.74 WILL work good for increasing torque on heavy vehicles.I have a set of 516's that out flow the 915s I ever had.Or Any Other STOCK Chrysler head(On a Vehicle including MW...).

Unless the port work is done to make it work. On the exhaust side the larger valves flow more. This is also true on many other heads. Ford GM ect.. I believe this is what causes the rumor that big valves kill low end torque. T & K Performance

Whoever put the 1.88's in them just cut the seat open and left a huge shelf at the bowl so I know I made at least some improvments. The price was right and I put a lot of time in them but not much money. I'm one of those guys that has to do everything myself but I'm never afraid to ask questions.

Yeah, Im sure lots of people have gone fast with them, but they just dont flow like other BB castings. 72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72. Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.

Thats about as much as most duel plane intake. So its a cheap easy to find closed chamber head. If you have better heads than for sure use them. But if not T & K Performance
