i'v got some stamped steel no-name brand valvecovers on my 302 and i wanted to know if they would fit my stock 351w... another curious question is, can you make the cast aluminum EFI valvecovers work on a carburated motor, if so how? just drill a hole for the breather and use the vaccum nipple on the oil filler neck to draw from with an inline PVC? or cut holes in both valve covers, one for the PVC and one for the breather?
