This clone (not non hemi) head uses the stock 25/27mm valves that have been worked over along with porting, milling .070, 10.8/18 pound green stripe racing springs, etc.

It's built with the budget guy in mind

This head is the perfect bolt on for your stock engine to wake it up with that stock cam and either a stock carb or vm22 or stock grind racing cam and 1.3 stamped rockers.

Remember you can bolt on the big pipe and carb but if the stuff in-between those items sucks, it's all for nothing.
