| I spoke with Jeff at Mr. Mummert's shop today. He says a set of heads are on the way to Ted Eaton's dyno for the first run. Wow. It is really happening!

| Good news I assume these may go on the engine masters engine or possibly a more conventional build.

Last night I dreamed of turbos. Tonight it'll probably be aluminum heads.

Holy Moly, I can even feel the ground beginning to tremble now,but I cant' tell if it's the awesome power of the NEW Y-Block parts, or the scrub lovers starting to tremble in their boots!!!!! CONGRATULATIONS JOHN and Big Thanks for making a dream come true!

| Great to see photo's of the new heads. Similar combustion chamber shape to other aftermarket heads I've seen for other american iron. Better combustion chamber size, decent dia valves, plenty of "meat'"to shave and up the compression, improved ports with better flow and all within the confines of using as many existing parts as possible. Seems to answer just about all anyone would want or expect. Good work John. The photo's (that I've seen) only show three sides of the heads! Some of the intake side would be great? On Dyno testing this is obviously a testing ground where they can show thier worth. I for one would be interesed in seeing a milder street engine tested as well as a hotter race engine. Obviously not every application can be tested but this would give a reasonable range for customers who would be interested. Also on reliability is a set of heads going to be tested on something that is regularly driven. Obviouly racing shows how they will perform (last) in the high temp high pressure environment that racing is, but daily driving has it's own set of extremes. Multipule warm up and cool down cycles, traffic, lugging loads I can see that these heads could be used in many applications, as many as there are Y block interest groups and be used in T birds, F100, trucks, a range of passenger cars from rods to full size cars. I'm wondering how reliability will be tested?

With 5/8" thick deck and 356-T6 material these heads should be more rigid than the OEM iron units. Somehow Ford managed to build 50lb cylinder heads and not put any material in the deck . The 5/8" deck also helps prevent thermal loss that an aluminum head would have if it were cast with the same thickness as a stocker.

| so here is what we have....the guys in the t-bird clubs don't want anything to do with 'not original' stuff.....that 'takes out' a bunch of sales.....the old guys with y-blocks don't seem to have $2000+ laying around for these heads either.......who does this leave??? rich guys with 55 fords? not too many of them around, i'll bet...and another thing...i was in the local 'classic car ' club in toledo,ohio for the last 3 years...i do add-on air cond. for older cars--(i'm a ex-mechanic) and had two complete vintage air 'kits' in garage loft--tried to sell them (half price) to anyone in the club (not just y-block people---any people (sbc,too-(chokeing sound here)--guess what--nobody wanted anything to do with adding a/c to their cars--they all 'liked them just as they were when new....and were not intrested...(and it can get pretty hot in toledo sometimes in the summer)....so who is left?? i can't see a whole bunch of drag racers popping out of the bushes...(am i wrong??) this was a great idea in 1995--maybe with the country in a kind of 'no money-out of work' thing going on now...this is hurting sales.....yes? no? somebody out there (john mummert?)...text me back and straighten me out on this......later ed
