89 Corvette Factory Performance Packages
I purchased an engine out of an 89 Conv. and transplanted it into a 1970 GMC 4X4. This engine seems far from stock. It has Trick Flow Heads, Edelbrock Intake and defiantly a cam upgrade. I am needing to order a push rod and guide plate for the head. The car this came out of is no longer around so not sure about the options. I am being told that the C4's in 89 came with a factory performance upgrade with Trick Flow Heads and intake. But can't seem to find anything on line about this fact. Is this true or not and either way where can I read up on what this upgrade included and how do I order push rods and guide plates making sure they are correct. Any information on this would be awesome.
Thanks Jason

No TFS heads were ever offered as a factory option.
Ordering push rods and guide plates should be not different than for any SBC: Confirm push rod length, then get hardened push rods and some guide plates. If the heads are "twisted wedge" heads, you may need TFS specific guide plates.
