Specifications:
What is the best low rise vortec intake manifold to use on a blue print 383. Need clearance under a corvette hood.
Where are these heads made
will this head work with roller cam if valve spring change to match cam
Will these heads H8002k, work with 350-7107 edelbrock intake manifold?
The most important question... what are the flow numbers across the range? All the specs are great but if they only flow 200cfm then I'm not interested.
If I took the stock heads off my newly rebuilt Chevy 350 could I use the stock pushrods and rocker arms on these heads?
Do these heads accept vortec style manifolds and center bolt valve covers?
Will these heads;138-H8002K work on a 1969 small block 307 V8, with an Eldebrock Torker-Plus Cam, 5002 and Eldebrock Performer Manifold?
