I have a fresh 1977 Mk IV with 781 heads, bored 0.030 over, zero decked, domed pistons (9.6:1 CR). The block is a series coolant flow and has not been modified (additional holes drilled between cylinders on exhaust side) for parallel flow.
? Will a fel-pro 1027 gasket cause an overheating issue?
?Does parallel flow really make a cooling difference ?
Asking the questions to see if I should swap out gaskets prior to putting in the car--and-- If so, should i switch it to parallel flow.
Please comment on my gasket choices as well. If I have to pull the 1027's, planning on 8180PT2 (or 502SD) if left series and 1037 for parallel.
Fel-Pro said the 1027 would work, but then later said to drill the holes and switch to 1037 "if" it was street/strip vs daily driver.
So, would like some input from folks with experience. To see if the gaskets need to be swapped out and is the switch to parallel worthwhile.
