Title: Heads
Post by: Spoonbill on August 31, 2017, 07:56:51 am

I have an 87 r10 305tbi 700r4 and I was trying to find out a little bit about these heads cause I have never heard of them. They are swirl port heads. I was just informed by chevy that these are just the iron version of the L98 corvette heads. That's pretty cool. Since they are corvette heads how much could I have them worked up without destroying them. Anyone got a clue??
