Thread: FE heads

Tweet

Ripped Again,
These are 63' 390 heads right? Okay, 1960 to 1965 chamber size: 68.1 to 71.1, exhaust valve:1.57, intake valve: 2.04, the
width(I): 1.34, hieght(I): 1.93.
width(E): 1.28, hieght(E): 1.84.

Now, this is all on these years 1960 to 1962, 352/390 special engines had a different hieght port size:
hieght(I): 234, the rest of the sizes are the same as the other 390's.

You need to get this book, it's called FORD PERFORMANCE the revised edition. This book is written by Pat Ganahl. From what I'm reading some of these heads have problems with some of the intake manifolds. Some of them you cannot use a medium or high rise intake manifold with. This is pretty confusing stuff and I don't wanna tell you the wrong thing. You can already see that the cylinder sizes are different, now they say physically that the 332/352/390/and a standard 428 head used exactley same valve sizes, 2.04 intake, and a 1.57 inch exhaust. Any of these heads will retrofit. To install them onto a 406 or the 428 you will have to chamfer the tops of the cylinders for valve clearance, according to Ford information the heads should not be used on a 390, because too large a notch would have to be cut into the cylinders. So, hopefully you see what I'm saying: you need to get this book and see for yourself and make your own decision. It gets very confusing when you start talking about 390's, 352's, and special 390's. There's a lot of different heads here that will bolt up but, you start having clearance and intake manifold problems where the ports won't match up. Sorry I can't be more help, but, Get the book! Hope this helps a little bit anyway.
