We ran the beast, only to find the driver side cylinder head is leaking coolant.

not sure where to get replacement heads, many vendors.

any advice? When you say leaking coolant where is it coming from?, it could just be a bad head gasket and what about the exhaust manifold bolt holes do some of them go to water? maybe remove the head and have it pressure or crack tested to confirm and then just look for a replacement on Ebay or Craig's list sometimes you can pick up a pair cheap.

Here is the first turnkey.

That's when we found out the head was shot.

The car was only on headers,  Enjoy!

Did I read right, Kuwait for paint?  For heads. Check all the local vineyards for 360 heads. Between Hagerstown to the shore ,Winchester to Norfolk you should be able to locate some

Yes sir,  I am originally from Kuwait.  A full paint job will set you back $2000 in kuwait. Show quality.

What about this?

Newest updates!

Ordered  these parts to be installed :

Mopar performance Alu.  Heads with upgraded valves 2.02
Edelbrock Air gap intake manifold
Cloyes timing set

This should bring that small Block back to life.

Please get rid of that plastic fuel filter.  That's a fire waiting to happen. :2cents:  Only run very short chunks of rubber fuel line.

It came with edelbrock setup as a recommendation,  are you sure?

Put a metal filter on it and run more metal line up to the carb.  Minimize the amount of rubber hose in the system.

Do you mind putting a link for suck setup?

I need to order parts in that case.

You can see that the factory used a metal filter and short 2" pieces of rubber hose on either side.  Then, another metal line was used up to the carb.  Rubber lines can dry out and crack.  Metal lines and filters are safer.

You'll just need a generic fuel filter and a straight piece of 5/16" fuel line.  You can bend it to go where you need it to.

Generic filter like this...

Heads and intake removed.

Decided to swap Cam,  rockers a push rods.

After a conversation with comp cams,  I decided to go with:

Their CL20-210-2 cams with 260/260 duration and 440/440 lift.  Also got their rockers and push rods.

Can you show a photo of where the water was leaking from the head?

This is the crack, it goes all the way through. My tech says it could have been fixed at a time before.

Also, timing chain and gears have been replaced.
