Wishing everyone here a very "Merry Christmas" and a "Happy New Year". You all stay healthy, Thanks, Gary in N.Y.

There's an easy way, we use the SBC "pills" to adjust the timing! I'll put some shots below! Thanks, Gary in N.Y. P.S. With our method you can get more than 5* if needed?

It needs to be pressure tested more than it needs "magging", pressure test shows everything? Thanks, Gary in N.Y. P.S. "Magging" is definitely OK though! Pressure test first, "mag" second! (Tip), whatever shop you choose for machining try to find one that has a block-plate to finish hone the...

Hi Stian, doing this for a living I would recommend changing all 16 seats regardless of your valve choice size? Most times the effort to go from the 1.500" the 1.600" valves doesn't get you that much gain unless you do more work! We can do around 175 HP on the 1.500" valve platform with all the...

Here's a shot to help show the difference between the "rotators" and the "non-rotator" assemblies! Like Ron says, you need much shorter springs with the "rotators" in play! "Happy Thanksgiving" to all!! Thanks, Gary in N.Y. P.S. Keep this in mind, you won't be able to use the 185 Isky...

The worst Flathead studs we've found can be drilled out using the magnetic drill press in about 10 or 15 minutes! Depends on the remaining length in the block? We simply "whiz-wheel" the top off, leaving about 1/4"-3/8" sticking up. We have the proper tooling to aline the drill press and the...

Hi "J", that's what we prefer to do to keep the costs down, use 16 old guides IF you have any? You can fit 16 used guides in one USPS small flat-rate box, runs about 7.00/8.00 shipped to our P.O. Box. Thanks, Gary in N.Y. P.S. It never made sense to me to need to buy 16 new guides and the...

Now's the time to put bronze liners/Stainless valves in and never have a "hung" valve anymore? You'll need no "additives" either anywhere? Thanks, Gary in N.Y. P.S. Bronze-line all 16 guides, install (8) Viton intake stem seals, and "never look back".

Lots more issues with the "new" Navarro's than what's apparent, including cooling hole misalignment? Do a search, I checked these out very closely for a recent blown build here? Thanks, Gary in N.Y. P.S. Had words with H&H back then will NOT use or sell them here no matter what! Here's a few...

Best fix here is weld a round cover on the pan and use a 1/2-20 GM drain plug welded in the center! We've done a number of these to date! Thanks, Gary in N.Y. P.S. Here's a few shots of the fix on a more recent build! If you look very closely this one also has our dipstick-adapter installed...

Some use "valve-rotators" depending on the years, some don't! If you change the valves you need the corresponding retainers to go with that specific valve! Thanks, Gary in N.Y. P.S. Personal preference here we don't use the "rotators" on any of our builds, our choice!

The only number you really need to properly degree the cam is the "ICL", this number tells the whole story! You don't check this with any lash included, it's normally done with the lifter riding on the #1 intake lobe and the dial indicator on the lifter! Don't confuse this with the "LSA", two...

Here's a link (https://www.fordbarn.com/forum/showthread.php?t=270880&highlight=cam+degreeing+pinning) to some interesting reading I put up here a while back! We degree check EVERY cam we install on EVERY build and move them when necessary! Thanks, Gary in N.Y. P.S. If you look closely to the...

Hi Joe, can you measure that pulley opening across? It appears (from the photo) the factory washer will not fit that particular setup? The OEM Flathead washer measures .312" (thick) x 1.560" (O.D.) x .660" (hole size). The Pontiac washer measures .310" (thick) x 1.625" (O.D.) x .655" (hole...

Hi Joe, appears to be not enough torque on the bolt, this will cause your problem. If it doesn't get enough torque it will eventually work its way out! What happens is having the correct "tension" on the bolt keeps it in place! To add to the problem, the OEM dampers are NOT a press fit to...
