I also have a motor that I got so I could rob bolts off of it and it's a laser block with the Saturn deal and it is an 85 and the head on it also has the pear shaped ports and its an 87.The head measures the same as my original but the guy I bought the motor from said he rebuilt it about 5 times...
I have that saturn key hole thing. I just measured the original head and it was 3 13/16" from the mating surface to where the valve cover sits and the one I am puting on is 4 1/8". So this sounds a lil newbish but what could we do about this.
