RAV is not the same as a stock Pontiac, Edelbrock is not the same as either. Our engines that have rocker shafts will also more than likely alternate intake valve placements. We made the decision to keep the stock locations as the OEM RAV engines for the guys who wanted a direct bolt on alum heads since Pontiac made about 200 sets to do a close as possible replacement head.
The head porter's head is required for valve movement which provides a huge advantage for heads up style performance trying to match performance of our competition in certain racing avenues against the newer style heads.

Lynn,
Don’t be silly, I know the intake valves were moved and if you read what was stated above you’ll see that I know the heads will have to be sent out to have a rocker shaft made. Short term I would have been ok with stud mounted rockers if a stud girdle was added and the only other change was to install the appropriate rocker studs. However this is not the case, the rockers are only rated for “450lb open” and guide plates will also need to be replaced.
