knowing a few people that have dealt with more i would sy find something else. from what im hearing they wont stand behind their work and when they worked on heads to make them flow more they flowed about 40 cfm less than the specs from the factory for the heads...just watch out...

well the "serious" car they build that i know has the motor out or it getting redone. cyl. werent perfectly round, the heads flowed 260 cfm instead of more than 305 cfm that they did out of the box. barely made any power. 110 miles and ate a quart of 20/50. and they wouldnt stand behind their work. they will do good work on their car maybe. but i know numerous people that have complained, which is why i decided to do my own work.
