Project is a 77 T/A 400 4spd. I built a 461 Stroker and upon my first attempt at starting it we encountered problems. I found water in cyl #6 which leads me to believe it blew a head gasket prior to even starting. We had been cranking it over quite a bit but weren't getting it to start due to some timing and spark issues. I will mention that a lot of my issues were from a defective Accel coil. My fault for buying junk Accel.

Anyway, so obviously I need to tear down and install new head gaskets. Is there a specific brand and part# anyone recommends?

Also I was told by an engine builder that it would be a good idea to install the gaskets wet to prevent this from happening again.

Engine is a 400 bored .035 with an Eagle bottom end. Ported 6x-8 heads for 9.5/1 compression. Cam is a hydraulic flat tappet from Crower. If you need anymore info let me know.

Thanks in advance to everyone on the forum!

I had that issue once, leaking in when not even done to be fired yet. 2 things: milled the heads a bit too far, and turned out the block's ends were slightly down; the middle of the block was higher than the ends.

crap I hope that's not my problem. When the heads were down they weren't milled really at all because I wanted to be conservative with compression so I could run pump gas.

What is the best way for me to check the deck of the block after pulling the head off? Like all I can really do is lay a ruler across and I don't think that's going to be more accurate than the machine shop

I believe you run a machinists straight edge across them and try to sneak feeler gauges under different areas to see what you're working with. It's somewhat rarer to have a block issue than a head issue.
