I'm sorry 318willrun I appreciate all your advice I just needed a little clarification here to make my mind work correctly. for some reason (I remember you saying that could be the problem part my memory) saying that the gasket kit you're recommending had the thicker gasket? I don't see any breakdown of that kind of stuff on the website but you were staying here just recently that it's thinner not the normal 39 but 26 I think it was if I look back here. which takes 15 away plus the 40 = -.055 total? I'll mill the heads if I can and if I can afford it. But that would mean that it comes with a thinner than stock head gasket? Again I hope this doesn't come off smart *** sounding or anything else really want to make sure I get the right stuff according to the stuff you've used before.
- First let me say, Jburch is right that .060 is the rule of thumb for "max" milling on small block mopar heads. I don't go the limit, because if it ever needs to be cleaned up .010, I (or the next guy) will have plenty of meat to do that. I have gone .045 before.
- 2nd, when I got my kit, the Fel pro head gaskets that's included are the 8553 head gasket. they are about .050 thick. Your factory tin head gaskets are around .020 compressed. So, the math is easy. You add .030 thickness from the head gaskets, but subtract .040 from the milling, you actually only netting about .010 - 015 thickness. If you went with the Fel pro 1008, you would gain another .012, but spend more money to get the 1008.
- Yes, small block valve springs are interchangeable. HOWEVER, do the 360 heads have rotators???? If so, that changes things a little.....
- Also keep in mind, the 318 heads can be a good option if you need to go that route, but I would certainly add about 25 bucks for porting stones and 8 hours of home porting
- You can also home port the 360 heads. I've done this twice for 318's, without redoing the block. Really works! Mildly home ported 360 heads cut .040 is a real healthy head for a 318.
- No need to apologize for anything.
