Use the "R" heads........

as they will drop the compression to a more acceptable level. The "H" heads are gonna be up there around 10.5.1, and that will prove challenging to buy gas that will work OK. The R's will make it about 9.8, which seems the limit for a car that weighs 3,800 #'s. The Low Riser intake you list will bolt right up, as well as the exhausts. It will also look "correct" compared to having the extra bolt bosses sitting there. If you install some CJ sized valves, and do a little porting, they are a very good head. One word of caution, you need to check the piston to valve interference if you have a cam that has a duration @ .050 lifter rise of more than 235 degrees, or a low Lobe Center Displacment angle or simply LC, (lobe centers). This is not to be confused with "intake centerline", which is just the intake's centerline in relationship to the crankshaft. These pistons have valve reliefs that are marginal at best, for even the stock size valves. If you have power steering, you will need to raise the engine about a 1/4" with washers under the motor mount stud. That will allow them to clear the slave cylinder without hitting due to vibration. Its easier than dropping the cylinder down. Looking for any 64 Marauder parts?
