girdle kit for stock head?
#19
The girdle for a stock head is a easy install.You need to have your cylinder fins cut and milled when you have it ported.RCR does this for a minimal cost.You replace the front cylinder nuts with long bolts and the four(4) head studs with longer ones.Works well.I had one on my race mod 400 with the stock head cut to a 15.5:1 comp ratio.Biggest problem is with head gaskets blowing with high comp.Always use stock gaskets.

i never had any problems without the girdle kit with HPD race pipe on trail mod,,even with 15.5 dome without the girdle was just as reliable as any troublems frees i had for the last 3 years...,,,now it is race mod so i put on the girdle.
