Ok, time for my 2 cents worth here. GEX....... patooie, I spit on there feet..... well, maybe I just give them dirty looks and the EVIL EYE..... but the feeling is the same. Someone came to me with an engine built buy a local shop... stocker 1600. It was a FI engine, in other words, FI heads on it. He had driven this engine for about 5,000 miles and it had always just been a bit on the hot temp side. When he came to me, he could not drive more than an hour without the engine getting very warm. So I check out all the variables.. Timing, points dwell, Valve lash.... Cooling items.. all were OK. Then a week later it just about froze up on the kid.. so I had to take it apart. When it was time to pull the rockers shafts off... oh my, It has GEX stamped on the heads. hum, part number looks funny.... they were bug FI heads with the first 3 numbers stamped over with 311...... ok, lets get um off and see whats up. They were stepped bug heads.... fly cut so deep the heads CCd at 40cc, a far cry from the stock 51cc... this poor kid was running a VERY high compression ratio, like almost 9 to 1 with deck height clearance figured in. Both heads had a crack from the exhaust valve seat to the spark plug hole and one between the valve seats... at 5,000 miles. I took them by the shop that had built the engine, and showed them. They said they had used GEX heads from a vendor for 2 months... and that they had to put at least half of the engines right with new heads. Well, they should have caught the fly cut and compression problem at assembly time..... shows how you should always try to get someone that cares when they put the engine together. If you can read the book, then try to do it yourself like the people on this page always say. I put 2 new Mexican heads on for the kid and the car runs great.... no heat problems. I would like to add that this engine had the lower compression. dished top pistons in it.... think what trouble there would have been with normal stock flat top pistons. Can you say Wholly Burning Square Back Bat Man?????
