Hi all. Finally got my 312 sleeved and its a top job :-)  . Now need to order everything to put it back together. My old cam was an edb and was going to replace it with a mummert Y265-s, only thing is he hasn't got any. Not looking for performance really just closest to original spec. Has anybody used the Isky E4, and which valve springs would you recommend? 
 Probably should also add that I intend to use standard pistons, I have the ford 4 barrel intake with a holley 390cfm carb and pertronix ignition.
