Hello all - I have looked through the archives but nothing addresses my specific situation.
I just rebuilt my original 350. Due to the fact that it is the numbers matching engine I did not have the block decked as it did not need it. Also, did not shave the heads. I spent a lot of time cleaning and prepping and smoothing the headi surface using an air tool with with a mildly abrasive pad to make sure I got all of the materials off of the block.
The pistons were 40 in the hole so I used a steel shim head gasket to up the compression a little. I had the motor running on the stand to make sure everything ran correctly prior to painting and putting in my car.
After letting it sit awhile I am noticing what appears to be some seepage between the head and block, right between each cylinder but not necessarily directly under the cylinder.
One important note. It is ONLY occuring on the passenger side. Also, on this same side I attempted to set the valves while running so things got REAL messy. But, again, I cleaned it VERY well with brake cleaner and wax and grease remover several times afterward. But, it still appears to be seeping.
Within the next week or so I will be taking it to the body shop to have painted and I want to be sure all issues are dealt with prior to this.
My question: Should I pull the heads and replace with composition gaskets and ditch the steel ones? I am not to excited about pulling it apart but now is the time if I am going to. Any thoughts? Thanks in advance. The advice I have received from this site has ALWAYS been RIGHT ON.
