So then, if I'm understanding this correctly, you guys are saying that even if you use a set of heads in which at least one or more of the ports are badly misaligned with the gaskets, there are guys who can make up for this with their expert valve job, and those heads will make just about the same power as that same valve job done on a set of heads in which most all the ports are fairly close to the size and shape of the gaskets ?
In other words, your saying that the shape and location of the stock ports will make very little difference to the power output of a stocker engine ? But the power is all gained from the valve job ?
That is VERY interesting ! I'm glad I ask the question. You see, I've been living in the world of bracket racing, since there is no class racing close by, or wasn't until recently. All I've heard is that you always need to port iron heads or at the very least do a simple gasket match.
But if what you guys are saying is true, then unless I'm shooting for #1 qualifier at Indy, I'd be wasting $ to pay "Heads Up" for their " better than acid porting" head treatment which they advertise on their website ?
Next question: The Pontiac engine shops get nearly $2000 for a set of 6x Pontiac heads with their valve job and CNC porting. So aprox what would it cost to have one of the Stocker head shops do just their magic valve job on a set. I don't need an exact figure. But for some of you guys who have had this type of head job done recently, was it about $2000, $2500, $3000, OR ?
Now for an opinion question. Do ya'll think it's possible to run just slightly under the index with one of the good Pontiac 350 or 400 combos, with just the usual 5 angle valve job that most Pontiac shops advertise ? Or is there enuff power difference in the real Stocker heads to make them a requirement to get you under ?
Hey, ya'll will just have to excuse the dummy questions.
I don't have any Stocker buddies to ask. So it seems to me that the best guys to ask are those who have been there and done it. OK ?
If I decide to build a Stocker, I don't want to buy a $1000 valve job, only to later find out that I needed a $2000 job from somewhere else to get the car under.
Thanks for all the info guys !
