    H8002K

    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/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.

    Will these heads work with the Edelbrock 7102 performer rpm cam?

    Asked by: NickNicosia98

    Will these work for .125 dome pistons?

    Asked by: Bobby1986
    These heads are normally used with a flat top style piston. You can check the piston to valve clearance and flycut the pistons if needed. A lot will depend on the camshaft being used.
