Thread: newbie says hi and has a problem

Tweet

I am answering because few others have so far. Drilling the new holes at an angle is probably possible but tricky. You could try it and if you ruin the manifold you might try to purchase an afermarket manifold for the early heads?????? Usually this problem occurs when later heads are put on an early engine and in that case Edelbrock makes a manifold for the late heads on the early block, but you are doing it the other way. Frankly I do not know if the early manifold will fit with the early heads on the later block, but before you drill maybe you should check out some aftermarket manifolds that might solve the problem. On the other hand, if you mess up the present manifold you will have to find another somewhere. Another suggestion might be just to buy new heads because they are less expensive than aftermarket heads. The Vortec heads are supposed to be very good and not very expensive so why go back to earlier heads except in extreme economic limitations? In my experience you can make a few telephone calls to manufacturere of manifolds and if you allow for them giving 80% correct information you can figure out the solution with a few phone calls; Edelbrock will answer e-mail questions.
