Dropped the block off at the machine shop today after work. :mrgreen:
Will be getting hot tanked, honed, and bored to 90mm. I don't plan on having the block/head decked as I am going to go with the felpro kit. I was leaning towards cometic however decided to go with felpro engine gasket kit.

More presents came in the mail for me today!

Wiseco 90mm 9.0:1 pistons
Eagle rods - H beam

Got some new parts in today. OEM water pump, oem oil pump gears, oem oil pump regulator kit, and valve keeper removal/install tool.

I got the head pulled off of the s14 KA today as I was planning to use the s14 head on the s13 block assuming the 14 head would be in better condition. Overall warpage I have not checked and I'm purely going off of looks, but the s13 head looks to be in much better shape than the s14 head.

I've noticed one of the exhaust valves is not seating correctly and could more than likely be bent. I will find out fully once I remove all of the valvetrain. I will remove all of the valves on both the s13 & s14 head and compare. Id really like to stick with the OEM valves however I may purchase a kit of BC intake/exhaust valves.

the s14 KA has seen better days.....much much better.

Cams out!

Labeled all of the intake/exhaust shims as I was planning on using the oem shims along with the s14 head, however I am rethinking at the point.

Removed head w/ upper IM

As you can see here in this picture that cyl 3's rear exhaust valve is not seating correctly.

Here is a comparison between the s14 & s14 cylinder heads
S14 left / s13 right

Here you can see the water ports in the HG are basically caked with dirty coolant/water/rust. This is another reason I'm skeptical about using the s14 head, even with a hot tank.
