During my engine build project, I came across fitment issues with my head gaskets. I decided to order replacements from Dan because his custom Cometic gaskets allow the lifters to be removed without removing the heads. I figured a long way down the road these would come in handy. I installed Dan's gaskets 2 weeks ago. As I was adjusting my rockers I found that one of my new lifters was stuck and needs to be replaced. Because of Dan's gaskets I don't have to remove the head saving me time as well as money for yet another new head gasket. I'd like to thank Dan for this well thought out gasket. - Tony - PRODUCT(S)/SERVICE(S) PURCHASED: - ViperSpecialty's Custom Cometic Head Gaskets .027" x 4.060" bore GenII - DATE PURCHASED: 6/28/2010 - DATE SHIPPED: 6/30/2010 - DATE ARRIVED: 7/2/2010 - PRODUCT/SERVICE QUALITY (1-10): 10 - CUSTOMER SERVICE (1-10): 10+ - WOULD PURCHASE FROM AGAIN?
