Engine Quest Heads

Has anyone had any experience with engine quest heads? They are based on a magnum casting, but you can get them with the earlier intake manifold bolt pattern. Valves are stock magnum (1.92/1.625) diameter. They are supposed to flow better than stock magnum heads. They were used on a 318 build in PHR that made 379 TQ and 402 HP without porting, and 386/425 with larger valves and porting. Here's a link to the engine quest site. They seem like a good deal to me. What do the experts think? https://parts.aaeq.net/IW_Products.m...TI_ITEM_SUBMIT
