$200 for AS&M sounds pretty reasonable for me.

AS&M will outflow SLP if both are new. If youve ported the SLPs heavily they should be better.

I see no good reason to justify the expense. It wont make much difference if you are not running the larger bases from TPiS or Accel.

However AS&M is going to flow better out of the box and probably has more port material.

Its up to you.

Haven't read much lately but always thought it looked like the Accel runners have the most material to port or extrude hone??

the AS&M's flow the best of ALL the large tube runners, brand new. the others can be ported to flow better, but it will cost a couple hundy $$. i agree with Vader, i don't think its worth the outlay to fully port the runners in those other brands (SLP, Accel, Edelbrock, etc.)

the AS&M's are as thin-walled as the stock units. they appear identical are are constructed just like the stock units, onlt difference is the tubes are larger diameter. folks going for the "stock look" often opt for the AS&M's on looks alone. you cannot port the AS&M's with any appreciable impact to flow.

for $200, the AS&M's are a huge steal. thats 1/2 price the cost of new. if they're in good shape (not all kinds of dents, etc.), i would leap at the change of buying them, faster than yesterday happened.

lastly, the LTR's will be useless without a much better flowing intake manifold, as also has been stated. its the main key to the weakness in the whole L98 intake to begin with.
