Engine Pushrod Length With Aftermarket Heads

[stang89bidges]

Is it normal to see a change in pushrod length from stock 6.272 down to 6.100 with new aluminum cylinder heads and 1.6 rockers?

Stock bottom end. No deck milling, no cylinder head milling.

Normally, no. Typically the pushrods will be longer.

6.4-6.5 with aftermarket inline heads
6.7-6.8 with TFS heads

Depends on which TFS heads, the 11R heads use an even longer pushrod than the old Twisted Wedge heads. 11R will be over 7.00".

Thanks Joe. You are correct. I was reffering to the TW 170 or 190 old heads.
