I am running 7.4's and I can here it. I am going to hold out until I buy a set of heads (looking at TFS) and then measure and change accordingly.

Voted for 7.4's.

Its best to check the preload, depending on how much the heads were milled, and how thick the compressed head gasket. I have used 7.400, and 7.450 and once 7.500.

I am using the 7.4s with the t3. I am running the 243 heads and there is some noise.

if stock heads I say 7.425. thats just over stock length and will make up mostly for the small base circle the cam was ground on. (assuming here its ground on a smaller basecircle like most comp cams.)

7.400 are fine, but the only way to be completely sure is to use a pushrod length checker.
