| + | ===Using an early style intake on an aftermarket Vortec-type head== | ||
| + | Many aftermarket Vortec style heads feature dual bolt patterns allowing the use of the early 12-bolt intakes. This has a dubious value. | ||
| + | |||
| + | Because of the height of the Vortec intake port, only the single plane 'raised port' race intakes have enough height to actually mate to the Vortec port- but even then the ports may be too wide or have other port fitment issues. The commonly available dual plane intakes do not have enough metal above the port to be ported to match the Vortec port, w/o having a vacuum leak or razor thin sealing surfaces above the ports. | ||
