Title: Mix & Match Motor Madness
Post by: Chevzilla on November 26, 2014, 06:43:40 PM

OK...So [attachimg=1]when I purchased my Tahiti the motor had these BBC 10114156 heads on it. Now I have a BBC 14015445 in my 84 P30 RV ... So if I swap out the heads will I be looking at any issues?

Looks like the heads (10114156) are gen V or VI, (non adjustable valve train) and the motorhome is a MK IV block, there is a gasket fot that app., (Felpro?) and the heads are likely 'peanut port', good for a heavy azz chassis/motorhome, low end grunt. What heads are on the motorhome now? decent oval ports like 781's or 049's? Ovals would be an upgrade over peanut ports for the boat.

If you are doing a cam too, the valvetrain should be swapped to adjustable, but on a stock smogger cam, the non-adj will be fine.
