A friend in Seattle who owns a HIGH QUALITY Engine Machine Shop asked
me for help.............so Im asking the "Experts" at YENKO.Net


A customer has a 69 z28 camaro. DZ302 engine. The car was made the second week of December 1968

The heads are 186 castings, they have press in rocker studs and are 1.94 1.5 valve sizes.

They have had a valve grind on them but other than the guide knurling they are virgin.

The outer head bolt boss' are chipped up badly and will need welding or head bolt washers.

The date codes jive l 3 8 and l 4 8.

The question I have, is this the proper build for these heads. 1.94 1.5 without studs and plates OR should I make them 202 1.6 with studs with or without plates?

I have seen 186 heads with 202 1.6 with press studs before off a 302 but not like these are.

Any help is appreciated.
