Product was as described and packaged well! Communication throughout prosses was also great! I will definitely be using them in the future with other projects.
Replacement heads for my 3.5 EcoBoost worked perfect. The kit had everything I needed. The customer service was excellent. Highly recommend this company.
They supplied me with a perfect set of heads to bring my 1999 Ford Ranger back to life. Ranger Frank has been in the family since the day he rolled off the showroom floor. Its great to have him back on the road.
Parts arrived as promised. Ported heads gave me that low end torque and high rev HP I was looking for! ...if only I did the cam at the same time.
