    Well she runs once again.Valves sound nice and quiet.It fired right up once I rotated dizzy 180, DOH! not sure how I goofed that up I put it in when I was doing valves.

    Anyway thanks for all the valuable advice once again.

    I would like to ask your opinion on re torquing heads?Does this need to be done on aluminum heads after a heat cycle?

    well pulled intake odd to find a bunch of coffee colored mud stuck to underside of intake..
    Post pics later..

    Not sure whats going on here checked all cylinders and they are running anywhere between 165 and 175 PSI ?Maybe a crack in the block somewhere? who knows?? Frustrating as hell though..

    If I need to get a new short block do you all think I should step up to a 351 will my heads work?Will AOD bolt up to it?
    Or just stroke out a 302 ?

    OK got heads off again both rear cylinders seem to be culprit I noticed the gaskets seem to have rusted and fallen apart at rear most water jackets..

    This time heads are going out.. should I use something on gaskets or just install dry?

    I got this off Edelbrock site..The note at bottom is probably where I went wrong?



    Head Gaskets
    Head gasket requirements change according the application for which the
    cylinder heads are being used. Use the following as a guide for head gasket
    selection:
    1. Engines with low or stock compression ratios (8-10:1), stock size head
    bolts (7/16"), and applications where the cylinder head is being used as a
    stock replacement or a performance upgrade with the stock piston
    volume, without nitrous or forced induction (blowers or turbos)- use Fel-
    Pro Head Gasket #9333-PT1. Victor Jr. heads are not recommended for
    these applications!
    2. Medium performance engines, 10-12:1 compression ratio, increased
    preload cyl. head fasteners (7/16" stud or 1/2" head bolts or studs), not
    recommended with nitrous or forced induction- Fel-Pro Head Gasket
    #1011-2.
    3. Highest performance racing engines. 12:1 and above compression ratio,
    1/2" cyl. head fasteners designed for the highest preload, engines using
    nitrous or forced induction-Fel-Pro Head Gasket #1006 Locwire. NOTE:
    This gasket will require modification of the head deck surface by a
    competent machine shop to Fel-Pro specifications.


    NOTE: When using Fel-Pro Print-O-Seal, or any silicone beaded gasket,
    you must apply a small strip of silicone to both the deck flange of the
    cylinder head, as shown below, and the same location on the surface
    of the block to prevent coolant from contaminating the engine oil
