Intake valley pan

I believe they are too low for a roller lifter, ie. it will hit. you could make one if you got some sheetmetal and a good eye. Could use the spider bolts as studs for the baffle. Agree, the lifter retention feature is far more important to me than the "oil control" after my pushrod eating 351C motor. I used to carry 2 spare pushrods in the glove box, no joke.
