Sure thing, for the cleaning, milling, "competition valve job", and install the springs the total is right around $225. The shop is Auto-Ron's in Davenport, Iowa. They do alot of performance motors locally here, always heard good things.

Heads weren't too tough to take off, just a little tight in there and i couldnt get the coolant lines off the back of the heads so we lifted both off together then took the line off once the heads were out of the car.

Pickin the heads up in the morning, will get pics then!

The machine shop didn't do that as part of the cleaning? Brake clean works pretty well but be sure to get it off before installing them.

I used a rag and pb blaster. Take each piston to TDC and use a little kitchen scrubber.

Make sure you switch spots on that green scrubber. I had an issue with the green pad peeling a little. You don't want to get that stuff in the water jackets.

QUESTION- Well, as you know i'm putting in an EWP, so i heard i have to plug the hole on the block with a freeze plug and RTV, but what about the hole on the timing chain cover? do i have to plug that? and if so with what? THANKS!

looks good

block doesn't have to be plugged

the cover we normally weld up, but a freeze plug can be used

I would use a fine wire wheel on a drill for deck surfaces and tops of pistons. The last thing you want in contamination from the scrub pad in the motor.

So just leave the block hole open but weld up the cover?

for the pistons i took each to TDC and spray a little brake clean and pb blaster then used a decently soft brush and scrubed a little bit then wiped off with a towel. There not perfectly clean but better than before.

Look'n good. You should send your computer off to Ion for a mail order tune though. I'm sure he'll work something out for you price wise, since you will be getting a dyno tune from him.
