Does anyone know what manifolds are best to improve a 502 mpi? I am looking for improvement in hp and a weight savings. Also what hp can be expected?

On twin setups, do you have to pull one of the motors? Or are the manifolds installed with bolts? My '94 had 2 studs per manifold, which would require removal of 1 of the motors. Don't know if same for my '99.
Also, Are the Stainless Marine manifolds the same as far as sparkplug access? My Merc/Gils were a pain.

Stainless Marine. Great price. Great warranty. I don't know why Teague likes Imco so much. They have the same gasket setup as stock Merc, which just asks for water leaks. CMI are great, but I'm not sure what happens when you put them on a stock 502. SM don't need any computer change. I thought CMI did. They are worth the price just to not worry about water leaks. CP Performance has them for about $1600 with standard risers.
