Cross drilled head/block

[moe44688]

Okay car is an 86 dodge 600. Motor is the factory 86 turbo I log motor with a garrett (always seem to forget this info lol)

So here's the thing. I am having a head done by Steve M and he drilled out the cooling passages under the exhaust ports. I don't know if my block is drilled.

What was the first year they started to drill the block/head?

I ordered a MP head gasket for an 86 turbo car. I don't want to drill the block, will there be a problem running the 86 MP gasket on a stock 86 block with a drilled head??

Thanks guys

I have run miss matched heads, blocks and gaskets and had no overheating problems.

87-89 t2's, '90 t4's, '91-93 t3's and the 89+ t1's. I believe some '89+ tbi blocks were also.

Thank you Shadow, I just wanted to double check.

Thanks for the info Pat.

If you get the 005 gasket, it connects the CD's for you so no need to drill the block or head per say. Barring that, I would drill the block, its easy to do and worth it. Are you going to upgrade to 11mm head bolts if you haven't already?

I thought my car used 11mm bolts from the factory?

Yes you should already have the 11mm head bolts. It was a running change during the 1985 model year where they switched from 10 to 11 mm.
