Didn't find an exact match, but did see 3986388....68-76...307/350. You sure about the numbers you posted?
The description fits, though. Two words - pure crap.
Two more words - LO3 better.

Porting LO3 heads is like spending money on pearls for a pig.
I said they were better than the heads on the van, not that they were good...
Get some LG4/L69 or LB9 heads, do some porting magic on them. Even if you have to spend $50 on the cores, you're better off.

spending money on pearls for a pig is ok i suppose but i've already prefered "like putting whipped cream on sh*t"
