Hey the FORD guys use them. Has anyone tried them on a BBC (not the FORD plates) Does anyone make them?? It is easy to make the intake ports flow but the exhaust ports stink. Is their a market for them if they worked??

Tinker, I'd like to talk with you about 6.5 modifications. Maybe a pop after work next week? We need to get together about those screwjacks too.

YEARS AGO THEY MADE PLATES TO GO IN OLD MK4 FACTORY HEADS BUT THEY NEVER CAUGHT ON AS THEY CHANGED THE EXHAUST PORTS AND MOST AFTERMAK\RKET HEADS RUN A 44 TALLER OR CLOSE TO IT EXHAUST PORT
THEY ONLY HELPED ALITTLE THEN ,YOU CAN STILL FIND THEM IN THE BACK OF CHEVY AND HOT ROD MAGIZNES EVERY NOW AND THEN

TRIPS-- Did you do any before and after flow # ??? What did you gain??? Yes the idea was to raise the port floor to increase the radius if the turn.

hey tink, no i never had the chance to flow test them but they look just like a set of air flow research exhaust ports. i copied the shape of the port floor. if you know how to port heads you would se how nice these pieces fit into a 990 head. i should have patented these items 20 years ago when i made them,sorry i didnt,but i cant see any reason why they wouldnt work. maybe jim v couldn enlighten us. i could make them for any other head also,cause i have access to a foundry. how about some gearcase holders for when the unit is off the mid section for storage,or to hold 10 of them for a repair shop or a marina for storage,were working on that rite now,i will let all know about this one!!! tripps. ps one of the reasons i didnt persue the port fillers is cause i knew that better was on the way,sad excuse isnt it
