I have a really nice set of oval port heads fully ported, 2.300 intakes etc.... They will include a flow sheet. Also I have a DART single carb intake 4150 style just polished and ported to these heads. All work was done by Bryce from Dr J's He is one of the best in the business. I was building a 454 pump gas deal for my jet boat. Sold jet boat and have no need anymore. let me know. Darren
