I am at the end my build of my motor. I have bolted on a set of brand new gt40p heads on my 302 roller block. The problem I am having is, the eldlbrock performer rpm intake is not fitting. Has anyone had this problem before. The machine shop has it now and currently milling the intake at a 45' angle. Any input is greatly needed.

The heads are new and have not seen a breath of gasoline. The intake is used. This is crazy because i have asked several people and they are clueless. I called edlebrock and they told me to have the machine shop mill them at a '45 degree angle.My machine shop guy has them done but will be a tight fit.Dont know what else I can do.The block is used but is in great shape.
one more question, has anyone had this combo. Edlebrock RPM intake with GT40P heads? The part number on the intake is EDL3820
not the bolt holes, just the sides of the intake are to big.Doesnt sit down flush.
yes, havent put them, on yet. I talked to the machine shop today. 7 hours total in machine work and it fits barely. He thinks the heads where milled, but we both thought they where bran new.Its gonna work. I will post then end result when finished. Cant wait.

What kind of horsepower am I looking at.
edlebrock performer rpm intake
1.6 rocker arms
E-303 cam
bored .30 over
Gt40P cylinder heads
9.5-1 compression
cold air
smog delete
ac delete
springs upgraded

Everthing else is stock-mass air, 19lb injectors stock throttle body.

I also added 3.73 gears and a tremec 3550.

Any pointers? Just a poor boy with a little extra money

We are now finding out that the gt40p heads are 60cc heads and thats prob going to be in the range of 10-1.
