compression

[gyt kid]

Before winter I would like to get the head shaved on my '94 vmax 600 the question I have is how much do I take off and if I should use the factory head gasket or a thinner one also does it pay to use two base gaskets to change port timing let me know if you have any other perfomance enhancements thanks

2 layers worked really well on them ..clean up the burble...some good clutching would help as well....and a single GYT pipe.

If you are going to cut your head dont peal you head gaskets! leave your head alone and just use 2 gaskets.works good
