113 Head Questions
A couple questions about the 113 d port heads.
First are these the same as came on the ZZ4 motor? What year vette's did they come off?
I am looking for some heads to put on my 88 IROC (iron head L98).
Will the 113's bolt right on with no problems? Do they use SA rockers or Non SA? The chambers are 58cc compared to 64cc on the iron heads correct?
I currently have SA Crane RR's and would like to be able to reuse them.
Thanks
Bob

Re: 113 Head Questions (Irocan)
I believe the EGR system on your IROC is internal wheres on the Vette with #113 heads it's external.
Check with the F-body forum, http://www.thirdgen.org/, to see how the guys deal with this issue. I know there had been much discussion of putting Vette Al heads onto the F-body engines.
