If we ran duals into a Y into single pipe like many Ilmore V10's, life would be better. Double amt of exhaust pulses per pipe. Would be almost like doubling the engine rpm.

Read this thread, have them make you a pair similar to these. These will not revert...

you have used several sets of risers on the same manifolds. were they pressure tested? it is only reversion if it is not a leak. you say fairly mild cams but they came in these engines. it is a pain but doable to degree cams in the engine compartment. you gotta hog out center of degree wheel so balancer socket fits thru.
