This is taking longer than I expected but I'm making progress. I found some oversize 1.70 / 1.44 valves on Ebay. Our old friend engnbldr had them listed at 59.90 with buy it now at $80.00 so that's what I did. With $10.00 flat rate shipping my total outlay for the valves is $90.00 which didn't seem too bad to me. I could easily spend twice that. Now to get the head in to the machine shop for seats and resurfacing. I'm planning to so some porting and cleanup on the head; should I do that before the other machine work? Also, how much, if any, should I relieve the chambers around the valves? |

Much more reasonable than the previous prices he was gloating about, for sure!

I relieved the chambers around my 1.72/1.50 valves as per Panics information on his site... http://victorylibrary.com/mopar/chamber-tech-c.htm We used a vertical mill. I also decked my block and left the head with minimal cleanup mill to avoid notching the bores. In other words all the relieving was in the head....all the machining to achieve compression was in the block. You will have to CC your head after relieving to calculate how much to mill the block to get your target compression ratio. .....and yes....its worth the trouble. |

That's very helpful information, thanks for the link. I had already decided to only mill the head enough to clean and square it then have the block decked to bring it to the desired compression ratio, probably around 9 or 9.5 to 1. Any suggestion on inexpensive but accurate equipment to cc the head? Summit has 3 kits. The cheap one is a grauated beaker that you have to tip and pour; I'm skeptical of the accuracy of that method. They also have a couple of stand mounted burrettes that should be more accurate but they are $110.00 - $120.00; I would like to split the difference but I'll spend the extra money if it's needed. |

My machine shop CCd my heads as part of the big valve thing. They roughed in the heads for big valves....I ported and radiused.....then sent the head back to the machine shop for CCing and finish valve work. (good to CC head with valve work done and valves installed) I then sent in the block for boring , decking , etc. Then we had some ales and watched a DVD...... |

I want to do as much of it myself as possible, not only to save money for the the experience and satisfaction of it. Now the ales and DVD I can go with. Here in a few I'm going to head for the pool with a Fat Tire in hand. |
