[super38834]

LLY heads they need 30 thousands to be true again if all the valves are cut and recessed 30 will every thing be ok? Will it make a difference on the crossover or the water manifold? will they need work to fit i need help here please

Yes it will make a difference on the Y pipe intake manifold. I took a lot less than that off and couldn't get it to fit with the gaskets installed.

I did my 05,5 thousands and had no problem but this one is not looking that way!!! It is an 05 to but looks like it may have gotten hot

[super38834]
