Hey all,
Sorry for the crudeness of the drawing. Not an engineer so I will try another.
What I am trying to describle is a bolt on lump port that mounts like an intake gasket (Lump gasket). It could also be milled (created) so it extends into the intake manifold to smooth the transition that LeeLites described. Sort of a ramp. But it may help the transition to the valve.
The red indicates the lump gasket.
I know its probably not exactly like the head. But hey, its my first L6 six Chevy.
I was even thinking of sheet steel(16 gauge?). By cutting it to the intake gasket shape. But on the ports only cut three sides. Bend it in with an angle, like a tounge.
Removing of the intake boss is another problem. I am aiming for a bolt-in idea that basic meat heads like myself can do. I can probably do alot more damage than good with a grinder. Is it easier to remove the boss (still learning whats what?) than the hole tapping for the lump? If I understand the rest of the bolt in lump work there's a good chance that a water passage can be struck.
By the way, if anyone makes one, make me one too please.
John C.
