The 245s are available with two chamber sizes out of the box (70 and 80 cc's) and can be milled anywhere from 60 to 80cc's, if necessary. The new 245s feature 2.125" intake valves and 1.600" exhaust valves, with 60/40 valve spacing, and come equipped with PAC (#1225) roller dual valve springs. Like all AFR heads and intake manifolds, the new 245s are covered by the AFR Lifetime Warranty.

"This is the highest flowing 23* cylinder head we have ever produced and we invested a lot of time optimizing this product. Achieving 350 CFM's in a non raised runner bolt on configuration is a milestone, especially in a mass produced affordable cylinder head. The neat thing about this product is it accepts commonly available headers and intake manifolds. With the flow curve this head features, 700+ plus horsepower on pump gas will be a cinch and in drag race configuration this head could flirt with 800 HP in an optimized package," said Tony Mamo, AFR Product Development Manager.
