Engine Rebuild Progress
I went to the shop to take some pics for you guys, I will put the rest of the pics on my website later on today, but here is a preview..
Pic on the lift..

Here is where the seal on the head leaked, exhaust gas was spilling from each cylinder.. and eventually ate away to the water ducts.. (whatever they're called)

What our pistons look like..

Chris,
When you get the block back together, any chance you could get your mechanic to take some measurements?
In particular, I'm looking for the piston to deck clearance, or how far the pistons are "in-the-hole". It just takes a simple dial gauge, and should be measured on the flat part of the piston. It will probably be between 0.010 and 0.030".
PM me or post here if you can.
Thanks

Problem is that it may be different because I am getting different pistons.. I can have them take the measurment anyways if you want. I guess you're trying to figure out how much gap there is for 11:1 compression??

Actually I'm really interested in teh quench clearance between the head and piston. I think that for a normally aspirated car it needs to be closer and we can do that with our head porting project. Hopefully your new pistons will have a similar quench pad (i.e. the dish is in the middle).
BTW, there is room for lots more exhaust flow on the stock head. The intake side is tougher to find gains on (but we're getting there). But gains of 10% on the exhaust side are quite doable. That would be really helpful for a turbo motor.
