trick flow heads spark plugs?

[saniutza]

i need a set of spark plugs for the trick flow heads.. i used to have the ford motorsport 2 degrees colder on my old heads(stock) but apparently plugs wnt work on the new heads... anybody running these heads with a s/c what kind of spark plugs?

Standard Mustang plugs don't work / fit on TW heads?

3923's gapped around .035" with a power adder.

I've ran 3923 and 3924 on my n/a TW headed 302 gapped around .050-.054"

They fit, but they are too short and don't extend all the way into the combustion chamber. Plus the aluminum heads need plugs that include the washers with them. Putting in the stock ones may tear up the aluminum at the seat..

cool, thanks. Glad I read this, I wasn't aware of that.

tnx man... why less gap with s/c and higher on NA?

So you don't blow the spark out with the increased cylinder pressure.

Trickflow is telling me to start at ".035 with Autolite 3924 with my N/A TW headed 302. Any reason why you used stock gap?

Thanks,
