I run the stock motorcraft plugs in all my motors. and thats what my motor builder reconmended too. But I have heard and seen good things about the E3 platinum plugs.

I second the motorcraft plug recommendation. There was a thread on here somewhere about plugs recently...I think I may have even started it. lol

NGK's run killer in Fords. They are long lasting and aren't easily fouled out with very tight heat ranges.

Have been running NGK's for years in 260's, 289's, 300's, 302's, 351W's and 351C's. No better plug on the market for Ford's. In my opinion anyway.

I run the Champion 3025 Platinum in my '71 351C 4V with a cam.

Q: Do your heads take the normal spark plugs?

A: No they don't.Like all good aftermarket cylinder heads they require a long reach 5/8 hex washer seat type plug like the NGK BCP6ES range,never use a tapered seat plug in alloy heads,you will damage them trying to get them out as the taper locks onto the alloy once it goes threw a heat cycle.
