a little more info these were on my car and I blew a transmission the first night it was running OKish. and now my wife is preg. and I need to stop playing so much. the engine was a 10.5 355 in a 3000lb car and it ran 11.7 so the heads work great there are only 5 passes on these heads and no street time. here are some pics sorry but my camera sucks and I don't have a spring compressor.

I know that the price is a little scary but this is a pic of another head I did the portwork on these were on one of my toys but I blew the trany the 5th pass. just around the time I got the carb to quit flooding and killing my engine it was a 355 with a solid cam 250@50 but the stall I recieved was also wrong and I had bad 60ft times. the engine should have ran a very low 7 on this pas I have a pic of below but the trany was slipping and I had only a 2000 stall. these are realy good heads.
