Time to rebuild, Opinions / Suggestions Options

[BPGREER]

Well it looks like it may be time to tear my engine apart. McMark was kind enough to point out my lack of compression this weekend. It looks like I have about 110 lbs on 2 cylinders, and 120 on the other 2. The motor has 64,000 miles on it (original), but it did sit for 17 years in a garage by the ocean. A guess is that the cylinder walls have pitted. I am thinking about rebuilding the top end. I realize there are some who disagree with ever taking this approach, but being that the engine has relatively low miles I hope it will work out. If I do choose this method, what would you all suggest in the way of cylinders/pistons sets, etc. I am running the orig Djet, so would going with the 96mm setup still function properly? I'm not trying to stray too far from stock (or to spend too much $$$), but wouldn't mind a little extra power. Thanks for any advice.

I have a split duration version of a web 73 that works very well for stock FI with a stock or 96mm bore and around 8-8.5:1 CR.

The straight pattern web 73 works ok, but having a dual pattern cam with the TIV head is the first step at making bigger power with cooler temps.

Going to a cam with a tad more duration and lift will cool the heads off (as much as 50 degrees) and will really help with down low and midrange power. I have seen improvements with gas mileage as well.
