    BluePrint Muscle Car Series Small Block Chevy aluminum Cylinder heads, designed for hydraulic flat tappet and hydraulic roller cams. Our 195cc intake runner heads have proven themselves time and time again at making more power than most other value priced heads. Ports and combustion chambers are as cast. Great port and combustion chamber design, combined with high quality 21-4n Stainless steel valves, Viton seals, and double springs make these heads a great value as well as making great power.

    H8002K is rated 4.0 out of 5 by 2.
    Rated 5 out of 5 by from Just as described I was looking for a good quality head in an affordable Package.. Been around Blueprint engines before so thought I'd give these a shot. So far they look good and quality is great. Will be installing soon hopefully They are what they say they are

    Rated 3 out of 5 by from Good and bad Have not run the engine yet, set to go on the dyno in a week. Great price for the heads, love the kidney shape combustion chamber and the design of intake runners and bowl area. Down side of the heads... they were full of metal shavings. Not a problem for me only because I ported and polished the heads. But if I was going to bolt them on right out of the box that could be a problem.

    Will these heads H8002k, work with 350-7107 edelbrock intake manifold?

    Asked by: NickT
    No, these heads need an intake that is made for pre 1986 Chevy cylinder heads.

    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.

    Asked by: Hpdracing
    Please refer back to our website directly, www.blueprintengines.com We will have flow numbers for this cylinder head listed there.

     If I took the stock heads off my newly rebuilt Chevy 350 could I use the stock pushrods and rocker arms on these heads? 

    Asked by: Sam73
    That would depend on the cam and lifter setup that you have in your engine currently. The best thing to do would be measure the setup once you have everything back together and order the correct length pushrod for the engine.

    Will these heads/springs work with solid cam/lifters? (ie non-roller, but solid not hydraulic).

    Asked by: Anonymous
    This head has valve springs that are made to work with a hydraulic camshaft not solid.
