Can I use 67 273 heads on my 69 318?

Yes and they will give you better comp with 57cc chambers or 60 I think on the 67 's as opposed to 62 or 63?

Those are book numbers...

The 67 heads will be about 63 cc and the 69 heads will be around 69 cc...

I have a 69 318 with no heads and also have a 67 273 engine. Can I use the 273 heads on the 318 along with the 318 hydraulic valve train? I'm trying to go cheap.

Yup as long as there 67 not 64-65. You could mill .45 off a stock head get some real good compression on the early 318s pistons are not the deep inside 9:1 even 9:5.

I wouldn't recommend milling the 67 heads... I put a set of 67 heads on a 72 318 with a .040" permatorque head gasket and the intake bolt centerline is too high and galls the intake bolts when I tried to install the intake... I have my intake at my head guy right now waiting to get milled for that set-up.... Once together, those heads and intake must stay together and not interchanged singly....

I don't get my heads milled to increase compression, I only have my head guy mill them to clean up the head to block face and make it true and square if it's off.....

Just bolting on the 67 273/318 heads with a .040" head gasket will lower the compression about 1 point...
