    PCE281.2051 is rated 1.5 out of 5 by 4.
    Rated 2 out of 5 by from bought these heads a few months back. finally was able to get them installed. I have about 1000 miles on my engine and i've been having a issue with the engine breaking up past 5k. checked my full msd system even though it is new. then dug into the heads double checking my geometry. everything was spot on. what I did find was that my seat pressure gauge showed I was only getting 100lbs on the seat to open. these heads are advertised at 145 on the seat. I checked each valve to find that they were all @100lbs. Iso now I half to pull my ne2w engine back down and send the heads off to have the valve springs replaced. I was key word very happy with my purchase not so much anymore.

    Rated 1 out of 5 by from Intake runner and bowl issues I bought these heads for a mild street build. Seems to be nice quality but the intake valve bowl is larger then the valve seat so the bottom of the valve seat creates an edge. The intake air must flow over the edge and the edge can't be removed as its the bottom of the pressed in valve seat. Jegs is awesome as always and going to send me the smaller runner 190cc set of theses heads. Hopefully more materal is left in the intake bowl so there is a seemless transition into the combustion chamber.

    If I have flat top pistons, what would be the compression ratio be? I'm looking at putting a small holly supercharger 144 on a 302 ford but I would not want anymore than a 9.5 compression ratio.

    Asked by: Shawn56
    This will depend on which piston you are using. Most of the applications will be over 10:1
