For the price you cant beat these heads that being said, Do not purchase a complete set of heads!!! First step make sure the head will bolt up to your block these heads are flawed, I had to bore out 6 head bolt holes to get it the bolt to thread on to the block, second I highly recommend sending these heads to a machine shop and have them properly install the valves they will not seat right if youre thinking you can just throw in some valves, geometry is the main reason I only give it 3 stars, youll have to do some serious research to get the geometry right. I had to shorten my valves a bit.

These guys are the best in the business. Great customer service and the products are top notch! Would recommend to anyone who is serious about racing.

Great products and great people to work with!
