Coolant flow

sounds good to me, appropriate equipment to do the job you need it to do.

would be interested to know if your manifold heat crossover was blocked off of indeed deleted from the design you have..

its another area where the basic idea of HEAT BAD dicates many peoples actions without due consideration for what and when the car will be used and whether an effective pump shot is necessary from idle on a cold day . and yes i know fuel has changed and the range of percolation and heat soak issues that can cause.

it's a can of worms that i should not open further.. :)
