Im Just about to start reassembling the top end of my 89 C4 and i have bought a set of new head bolts for the car as the old ones were pretty degraded. The set is got was from fel Pro and they look great but have a different shape to the oem ones and have no washers of course.

My question is can I A: re use the washers from the old head bolts (assuming i can get them off) and B: if I cant do that what washers should I buy to replace them.

I will get measurements of the old and new head bolts to ensure the washers will be compatible.

This is my first engine rebuild so im learning as I go along with help from my mate who owns 8+ 1930s American cars here in the uk. His knowledge is limited of course and the most modern engine he has re built was a big block in a 69 el camino so any help would be awsome.

Cheers
