Default Heads are in

Finally recieved my 5.3 heads from Bo White. The extra long wait was due to a error by the machine shop, but Gunnar @ Patriot was able to fix em' better than new. They are port/polished & milled .018" by Bo & were fully assembled by Gunnar with the Patriot Gold Dual spring kit. I could not be happpier with the quality of the work done by both parties & the flow numbers looked great for a stock cast head. They should compliment my 224/.581 114 cam nicely.
